Mechanical Advantages of Fenestra 


Fig. 3 


The Five Essentials of Steel Sash 
1—Sufficient strength at the joint. 
2—Rigidly attached, adjustable butts. 


3—Weatherproof, double-contact 
weathering on ventilators. 


4—Ventilator controls that provide 
efficient operation. 


5—T-bar mullion insuring weathering 
between sash. 


1—Strength at the Joint 
The construction of the Fenestra 
joint is based upon the patented inter- 
locking of the vertical and horizontal 
muntin bars of the sash, permitting 
them to run continuously from head to 


Fig. 4

sill and jamb to jamb. This inter- 
locking method retains thirty per cent 
more steel at the joint than any other 
method of joining. It gives the sash 
maximum strength against wind pres- 
sure and the vibrations caused by 
heavy machinery. 


The bars are solid rolled steel 
sections, 134’’ deep. They are ma- 
chine cut and fitted together with a 
weather-tight union, which makes 
welding unnecessary and reduces the 
possibility of corrosion. Figures 1 
and 2 show the horizontal and vertical 
bars with the metal removed. Figure 


3 shows the two bars after the vertical 
bar has been prepared to receive the 
horizontal bar. Figure 4 shows the 
completed joint. Note the graceful 
outward curve of the vertical bar. 
This is the distinguishing feature of 
Fenestra Windows. 


2—Adjustable Butts 

All ventilators are horizontally 
pivoted 2 inches above the center by 
means of two external, adjustable, 
solid rolled steel butts. Every butt 
is composed of two members, one 
double riveted to the jamb bar of the 
ventilator and the other to the adjacent 
bar of the fixed portion of the sash. 
Each member has an ear which 
projects beyond the plane of the sash

and through which the butt bolt is 
fastened. This makes it easily acces- 
sible, and aslot in the member attached 
to the fixed portion of the sash permits 
adjustments. The butt bolt is pro- 
vided with a shoulder upon which the 
ventilator turns. Its lower part is 
threaded to receive a nut for the 
purpose of tightening the pin after 
adjustments have been made. This 
construction may be seen clearly by 
studying the illustration on page 3. 

The overlapping weathering makes 
the butt storm-proof. Asthe ventilator 
is closed, the weathering of the movable 
section fits down -inch over the 
weathering of the fixed section, forming 
an overlap which sheds water and gives 
surface contact. 


3—Ventilator Weathering 


Two-point, flat-contact weathering 
is used on all types of Fenestra Venti-

at the sill 


lators. At the head and sill, where 
extra heavy sections are used to 


STAY BAR 


strengthen the ventilators and prevent 
sagging, the weathering members have 
long down-standing legs that form a 
drip on the exterior. On the interior 
of the sash, long legs project upward, 
thus forming a double contact. Further 
protection is given by the turned-down 
lip on the interior of the head weather- 
ing member that forms a baffle for air 
currents. This feature may be seen 
by studying the head details on pages 
11, 12 and 18. To guard against 
leakage at the sill, the weathering 
member on the sash is mitered and 
turned at a right angle, all seepage 
being thus eliminated. Any water 
which may collect from condensation 
is carried to the outside through weep 
holes cut in the sill member of the 
fixed portion of the sash. 


4—Ventilator Controls 

Fenestra operating hardware is at- 
tached to the ventilator by the Z-bar 
bracket. This is a solid steel section 
rolled with a fillet in each corner which 
gives it double thickness at this point 
and, therefore, greater strength than 
can be obtained in any other way. The 
bracket is securely attached to the 
bottom section of the ventilator by 
means of three rivets and cannot work 
loose. It is punched for either of the 
standard operating devices. 

Engineers and architects have de- 
manded a self-operating and fool-proof 
method of locking ventilators in place. 
This demand has been supplied in the 
Fenestra cam latch, which is of 
pleasing design, strong and substantial, 
and is attached to the solid rolled steel 
Z-bar bracket, which is securely riveted 
to the bottom rail of the ventilator. 

In closing the ventilator, the cam 


ZLo-BAR BRACKET 


latch rides up over the weathering and 
falls inside, locking the window, as 
shown in the illustration. 


The cam latch and stay is supplied 
as standard on Fenestra Sidewall Sash. 
To open the ventilator, the cam latch 
is lifted by the right hand, while the 
left hand pushes the stay outward until 
one of the notches along its lower edge 
engages the weathering at the bottom 
of the ventilator. 


The cam latch and chain are 
supplied when specified on Fenestra 
Standard Sash. The chain extends 
from the handle of the cam latch over a 
pulley at the top of the ventilator down 
to within easy reach and back to the 
handle of the cam latch. 


Cam latch and chain 


A slight pull releases the cam latch 
and at the same time pulls the ventila- 
tor open. A chain cleat, fastened to 
the sash or to the wall below the 
window, engages the chain and holds the 
window open. KR

held together in the center by means 
of our standard T-Bar Mullion. 

The wings of the mullion are punched 
with holes spaced exactly like similar 
holes punched in the jamb bars of the 
sash. When the sash are installed and 
trued in the opening, the holes in the 
sash and in the mullion will be exactly 
opposite so that stove bolts with wash- 
ers (supplied without extra charge) may 
be inserted easily. 


Above is a photograph of two Fenestra Warehouse Windows (Z-54161) installed in con- 
crete with vertical and horizontal cross-sections showing dimensions and installation details, 


The term ‘‘Sash Dimension Point” is used to designate the points from which the height 
or width of a window is measured. These pointsare 3%’ outside the web of each jamb 
bar—see explanation on page 11. 


NOTE: Provision should always be made for anchoring mullions at the sill. 
The stem of the T-Bar Mullion must always be turned out when a steel sill is used, 
otherwise a special cut-off is necessary.

It has been our privilege, based on 
15 years’ experience in unusual day- 
lighting and ventilating problems, to 
make suggestions that have increased 
the efficiency of proposed buildings 
very materially. 

The Showers Building shows the 
effective lighting and ventilating of 
a large floor area—double monitors 
with V-shaped roofs supplement the 
sidewalls to provide efficient working 
conditions. 

Scores of short saw teeth running 
crosswise of the building flank the 
central monitor in the Dodge plant— 
a model arrangement of lighting and 
ventilating units. 

These are typical of scores of 
buildings where the experience of 
daylighting engineers has been of 
assistance in working out econom- 
ical and effective designs. 

Where service of this kind is de- 
sired, our Engineering Department is 
at your command without obligation.

Saves Time and Money 


Certain popular types of Fenestra 
Solid Steel Windows have been stand- 
ardized. These are made in quantities 
and carried in stock in Detroit and in 
other cities ready to supply rush de- 
mand. They are made from standard 
material to accommodate 12” x 18” and 
14” x 20” glass exclusively. They are 
fully equipped and can be shipped 
quicker than any other windows. We 
recommend sash in 14”’ x 20” glass size, 
as they cost less per square foot than 
the 12’ x 18’ type. They answer all 
the usual building needs. 

An ideal building from the standpoint 
of sash economy is one designed for 
Warehouse Stock Sash exclusively. If 
this cannot be done, use Warehouse 
Stock Sash wherever possible, and give 
Standard Sash the next preference. 

We shall be glad to give you the 
address of the warehouse nearest you. 


How to Use the Table 


Suppose you have a window opening 
7’ high by approximately 15’ wide to 
be filled with stock sash. You want to 
know the number of units needed, their 
height and width, and the number of 
mullions necessary. 

You probably would use the 14” x 
20” size, if possible, because the larger 
glass size reduces the cost of the sash 
per square foot. In the column headed 
“Glass Size 14” x 20’,’’ you will find 
a height dimension of 6’ 1034’’—this is 
probably close enough to 7’ to serve 
your purpose. Glancing down the 
same column you find an over-all width 
dimension of 14’ 111%”, and opposite 
this figure, in column three, you find 


the number 12, which means that the 
bay of sash when complete will be 12 
lights wide. In the next column, the 
figure 3 indicates that you will need 
three units of sash and therefore two 
mullions to join them together. The 
last column gives the figures 4, 4, 4, 
which indicate that each of the units 
will be four panes wide. Therefore you 
will want to use three units of Z-44181 
Fenestra Sash and two Z-4 mullions. 


Ventilator Lights Cut Down 


Ventilator lights that abut on the top, 
on the sides or on the bottom of the 
ventilator, must be trimmed one inch 
(1’’) along the abutting edge. Care 
should be used to see that the glass is 
cut full to the dimensions specified. 
The picture shows a standard glass lay- 
out for a “Z”’ type sash—one that will 
accommodate glass 14” x 20”.

Horizontally Pivoted Sash 


Standard Installation Details 


Sash Dimension Points 


The outstanding leg on all outside bars of Fenestra 
windows is intended to imbed in the building construction 
14", In measuring Fenestra windows, therefore, we dis- 
regard the part that imbeds in the building and make our 
dimensions exactly the same as the masonry opening. 
This places our ‘‘Sash Dimension Points” 14” ee from 
the tip of the outstanding /eg, or in other words, 34" out 
from the web of the outside bar. 


Prepared Openings (Page 10) 


We strongly recommend the installation of Fenestra 
Sidewall Sash after the walls of the building are practically 
completed. 


In every case, regardless of whether single units or 
combinations of units are to be used, the opening should 
be prepared in accordance with the dimensions shown 
in the installation details on the following pages. Re- 
bates and angles are shown that have been accepted by 
builders and contractors as the best building practices, 
and these should be closely followed. 


It is not good practice to place the sash upon the sill 
and then construct the walls around them. Long experi- 
ence of engineers and builders familiar with the erection 
of steel sash has proved this method unsatisfactory. 
Regardless of the care and refinement used in adjusting 
such installations, they are frequently faulty. 


Fenestra Erection Service 


The Fenestra Construction Company, a subsidiary 
of the Detroit Steel Products Company, offers architects, 
engineers, contractors and building owners, the service 
of an organization especially equipped and trained for the 
erection of Fenestra WindoWalls. 


Under separate contract, the Fenestra Construction 
Company will assume complete responsibility for the 
shipment, handling and erection of Fenestra products, 
from the time they are manufactured until they are 
installed in the building. 


Glazing Fenestra Sash 


All Fenestra Sidewall Sash should be bed _ puttied, 
then the glass inserted and held by means of Fenestra 
spring glazing clips. Clips are supplied, 4 for each fixed 
light, and 6 for each ventilator light. They are put in 
place with the putty knife, as shown in the illustration, 
after which the sash is face puttied. 


Note—When inserting glazing clips, first place the clip 
against the glass, then spring the free end into the hole 
provided for it.

Continuous Monitor Sash 


Specifications 


All Continuous Steel Sash shall be Fenestra standard 
(top hung, center pivoted, or fixed) type, with vertical 
muntin bars spaced two feet on centers. 

All runs shall have one-foot stationary panels at the 
ends and two-foot stationary panels between swing 
sections, all as shown on engineer’s details. 

All sash members shall be solid rolled steel sections 
of standard Fenestra design. 

All vertical muntin bars shall be substantially 
riveted to the top and bottom rails of the sash. 
All sash shall be hung by means of malleable iron butts, 


with 3” pins, placed inside of girts and spaced 
four feet (4’-0’’) on centers. 

All glass shall be held in place by Fenestra angle 
glazing clips, located near the top and bottom of each 
side of each light. 

All glazing shall be done under another contract. 

All sash shall be given one coat of red mineral paint 
before shipment. 

All Continuous Steel Sash shall.be installed in the 
building by the sash contractor. 

All flashing shall be done under another contract. 


Monitor Sash 


Fenestra Continuous Sash is designed 
for use in monitor and saw-tooth roof 
construction where the plane of the 
windows is onaslope. It may also be 
used in vertical planes, where the 
builder desires this form of window. 
The chief advantage of this construc- 
tion lies in the fact that it provides 
easily and rapidly a continuous open- 
ing from one end of a building to the 
other, at the same time furnishing a 
canopy of glass and steel which protects 
the aperture against weather. 


Construction 


All Fenestra Continuous Sash are 
made from solid rolled steel sections. 
The head member is a special angle. 
The sill is a rolled section of special 
Fenestra design, with a long down- 
standing leg, bent at the end to make 
close contact with the building con- 
struction. 

The intermediate muntins are T- 
bars, and the members forming the 
ends of the units are special angles. 
All members of the sash are accurately 
fitted and strongly riveted at the joints 
to form a standard panel, these panels 
being joined end to end when erected 
in the building, to form one continuous, 
unbroken sash of almost any desired 
height or length. 

Riveted assembly insures a strong, 
tight, positive joining of members, with 
sufficient flexibility to withstand un- 
usual strain without the danger of 


Weep holes are pro- 
vided in the sill 
member, to prevent 
water from collect- 
ing at the bottom 
of the sash and 
seeping through.

section at the head,

tion at the sill and

This construction is 
the same on all types 
of Fenestra Continu- 
ous Sash.

as an extra where desired. 


cracking or breaking due to an uncer- 
tain weld. 

A specially designed weathering cap 
at the end of each run overlaps and fits 
around the edges of the ventilating and 
the fixed sections, allowing for expan- 
sion and contraction in the sash while 
providing thorough weather protection 
and reducing heat losses. 


Standard Heights 

Fenestra Continuous Sash is manu- 
factured in four heights, these being 
standard whether the sash are Top 
Hung, Center Pivoted or Fixed. These 
heights are: 3’, 4’, 5’ and 6’. Sash of 
special height may be secured where 
desired, but naturally require longer to 
manufacture and can be supplied only 
at an increased price. 


Standard Widths 
Standard units of Fenestra Con- 
tinuous Sash measure 20 feet in length, 
the dimension points being equal to 
the clear opening. Smaller units may 
be used in widths varying by 2’, as for 


instance, 8’, 10’, 12’, 14’, 16’ and 18’. 
We have found, however, that in the 
vast majority of cases, 8’, 12’ and 20’ 
widths answer all purposes. These 
widths provide for the economical 
arrangement of operator arms and per- 
mit the punching of steel work on even 
4’ 0’ centers for butt attachment before 
it is erected in the building. 

Units coming at the end of arun take 
the same standard widths, but include 
a 1’ fixed panel. Thus a 20’ unit 
coming at the end of a run would be 
composed of a 1’ fixed section and a 19’ 
ventilating section. 

No odd-inch dimensions, such as 
16’ 6”, are used. 


Joining Standard Units 


Where two or more units of Fenestra 
Continuous Sash are joined to form one 
continuous run, the joint is always 
made beneath the center of a glass 
light and is thus absolutely weathered 
without the employment of weathering 
caps. Gusset plates, which follow the 
contour of the sash bars, are used at 
both head and sill. 


Weathering Members 


At the ends of all swing sections, 
stationary panels one foot wide are in- 
stalled. These panels are shown in the 
picture at the left of this page and are 
standard, whether the sash are Top 
Hung, Center Pivoted or Fixed. 

The end panels afford the best means 
of effecting a weather-proof connection 
between the sash and the building, 
allowing for minor irregularities in 
structural work around the prepared 
sash openings. 

Between all swing sections a two-foot 
stationary center panel is installed, as 
shown in the picture at the right. 
This panel, which is standard on all 
types of Fenestra Continuous Sash, al- 
lows ample clearance for structural 
members that may interfere with the 
operation of swing units. 

The union of the stationary and 
swing units is made weather proof by 
means of a channel section which com- 
pletely covers the joint when sash 
is closed. On Top Hung Sash this 
weathering channel is bolted to the 
swinging portion as shown in the pic- 
tures above. Where Center Pivoted 
Sash is used, the weathering cap is 
hinged at the top and swings outward 
as the sash pivots. A guide clip, pro- 
truding from the sill member of the 
sash, slides in a channel under the cap, 
assuring alignment. This is shown on 
page 31. 


Figure 2 


Here are the 2’ center panels installed between 

swing sections of Continuous Sash. Notice the 

storm panels and the weathering members on 
the ends of swing sections. 


Flashing 


Although Fenestra Continuous Sash 
is well weathered, flashing should not 
be omitted. Detroit Steel Products 
Company does not furnish or install 
flashing, roof, nor collateral steel work. 
This material should be furnished as 
part of the building construction. 

To assist the architect and engineer, 
details of the most approved methods 
of flashing Fenestra Continuous Sash 
are shown in the installation details on 
the following pages. 


Fenestra Continuous Fixed Sash 


Fenestra Continuous Fixed Sash is 
of similar construction to Top Hung 
Sash, except that the hinges at the top 
are omitted and no operating mech- 
anism is supplied. 

In place of the hinges, angle clips 
(Part 619) are supplied with the sash 
for use at the head, these being bolted 
directly to the building construction as 
shown on page 26. 


At the sill, Part 433 clips (also shown 
on page 26) are supplied without extra 
charge, these being bent around the 
steel work to hold the sash tight against 
the building construction. 


Glazing 


All Fenestra Continuous Sash are 
glazed from the outside. One-quarter- 
inch, ribbed, wire glass is recommended, 
the ribs running vertically. The glass 
must be firmly imbedded in steel sash 
putty, after which Fenestra angle 
glazing clips are bolted to the muntin 
bars at the sides of each light. 

The following table shows the glass 
sizes for standard units of Fenestra 
Continuous Sash: 


Sash Glass Glass 
Height Width Height 
SU 23144" 2’-914"" 
AZO 234%" 3/-914”’ 
5/-0”" 2314" 4-94" 
6’-0” 231%" 5/-914"" 


Fenestra Continuous Operator 


The selection of a properly designed 
operating device is just as important 
for the satisfactory installation of Con- 
tinuous Sash as is the selection of the 
sash itself. Many a builder has been 
disappointed in his ventilating scheme 
because, after everything was done, he 
found the operator would not push out 
the sash to provide the necessary open- 
ing. 

Fenestra Continuous Operator is the 
product of the careful design and long 
experiment on the part of our engineers. 
It combines the principle of ‘‘straight- 
line motion” and therefore maximum 
power, with a design by which this 
power increases faster than the load 
increases. These features, coupled 
with the refinements and improvements 
which have been put into effect within 
the past few months, make the Fenes- 
tra Continuous Operator an important 
factor in the satisfactory solution of 
any Continuous Sash problem. 

Details of Fenestra Continuous as 
well as Fenestra Worm and Gear Oper- 
ators will be found on pages 39 to 56 
of this catalog. 


Erecting Continuous Sash 


All monitor construction is a movable 
roof and only men experienced in the 
erection of steel sash and operator can 
satisfactorily install it. 

The Detroit Steel Products Company 
saw the need for a specialized erection 
service and organized the Fenestra 
Construction Company to supply it. 
This is the first organization built up

by any sash manufacturer to assure 
acceptable installations for customers. 

Branch offices are maintained at 
Detroit, New York, Philadelphia, 
Boston, Hartford, Buffalo, Chicago, 
San Francisco, and Birmingham, From 
these, erection service can be extended 
to take care of almost every builder’s 
needs. 

These offices are equipped to follow 
shipments, look after prompt delivery 
at the building, install sash, erect oper- 
ator, and attend to every detail. 

It is to our advantage to be sure that 


a8) 


our materials are not only made cor- 
rectly but installed correctly, and we 
are ready to assume the responsibility 
that such a service implies. Our con- 
struction men are all experts in the 
erection of steel windows, and can 
therefore relieve both owner and con- 
tractor of detailed supervision. 

When Fenestra Service and Fenestra 
Solid Steel Windows are specified, the 
customer can forget that part of the 
building and be sure of satisfaction 
when the completed work is turned over. 

Fenestra is more than a name; it isa 
guarantee of complete window service.

Top Hung vs. Center Pivoted Continuous Sash 


The use of Top Hung Continuous 
Sash or Center. Pivoted Continuous 
Sash should depend entirely on the 
nature of the building and the activities 
it covers. Both types have advan- 
tages and disadvantages. 

Top Hung Sash requires less expen- 
sive collateral steel work and’ provides 
protection from weather. On _ the 
other hand its construction is such 
that it cannot providé a 100% open- 
ing, while the weight on the operator 
necessitates either a longer period 


for opening and closing or the in- 
stallation of more expensive operating 
mechanism. 

We seldom recommend the use of 
Top Hung Sash in vertical plains, either 
in roof or in sidewall construction. 

Center Pivoted Sash requires a can- 
tilever support, which issomewhat more 
expensive than that required with Top 
Hung Sash, and its proper alignment 
requires care. Where ventilation is 
important, however, it is far superior 
to Top Hung Sash as it may be opened

to a horizontal position, giving 100% 
ventilation, or even beyond the hori- 
zontal, in which position its effect is 
virtually that of a chimney. It is un- 
usually rapid in operation and the 
mechanism is far less expensive, both 
in first cost and in maintenance.

Designed by the Company’s Engineers 


This type of Continuous Sash is most 
frequently used in monitor or saw- 
tooth roof construction where the plane 
of the sash is off the vertical. It is 
also employed in sidewalls where the 
builder particularly desires this type of 
construction. 

It is hinged at the top under the pro- 
tecting hood of a Z-bar or angle section 


Commonwealth Steel Co., St. Louis, Mo. 


and swings out at the bottom to form 
a weather-protecting canopy of glass 
and steel. 

Heavy malleable iron butts, spaced 
4’ 0” on centers, are attached on the 
inside of the building construction and 
are thus protected from weather. 

The swinging section overlaps a 2’ 
glass storm panel at each end of the run. 


This type of Continuous Sash can be 
installed in runs of practically any 
desired height and length. The swing- 
ing section is opened and closed by Fen- 
estra Continuous Operator, manually 
or electrically controlled. (For details 
of Fenestra Operators, see pages 37 


to 54.)

Three decks of Fenestra Continuous Top Hung Sash in the valley roofs, and two decks along the top of the sidewalls above the 
cranes, provide exceptional light and ventilation in this steel tubes mill. Seventy thousand square feet of sash were used. 


“We draw our labor from men who are used to the modern working conditions of automobile plants,”’ says Mr. R. H. Phillips, sec- 
retary and treasurer of the company. “These men won’t tolerate the heat and darkness of the old-fashioned mill building. Fenestra 
keeps our people satisfied and helps speed up our production.”

Ninety-one thousand six hundred and seven square 
feet of Top Hung Sash light and ventilate this 
mammoth machine shop. The swing sections are 
operated by Fenestra Continuous Operators, the 
units of the monitors being electrically controlled. 
The glass canopy, formed when the sash are 
opened, makes it unnecessary to close the windows 
during inclement weather. Fenestra Continuous 
Top Hung Sash is also used in the bays of the 
sidewall, the upper three tiers being fixed, while 
the lower four tiers are manually operated by the 
use of auxiliary powers, three bays being operated 
froma single station. Some idea of the size of 
this building may be gained from a glance at the 
single doors which give access to the building 
directly under the big bays of sash. In the upper

Fenestra Continuous Sash, both top hung and center pivoted, are used on these buildings, over runs of Fenestra Continuous Fixed 
Light Sash. The high monitors suck heat and smoke to these outlets at the highest points in the building.

This company figures that Fenestra WindoWalls and Continuous Sash, such as used on this building, give a saving of $5,000 a 
year as compared to the same building equipped with wood sash. This saving includes economy in repairs, depreciation, illumi- 
nating cost, and labor turn-over, in addition to the advantages derived from fire protection and increased production due to 
better light and ventilation. Over 10,600 square feet of Fenestra Continuous Top Hung Sash were used in the monitors alone.

The Akin roof as used here is an economical design, particularly where a crane runs the full length of the building and where 
evenly distributed daylight is desired over a large floor area. The Fenestra Top Hung Continuous Sash in both monitors and 
sidewalls forms a canopy of glass which makes it possible for the windows to remain open even in stormy weather.

Center Pivoted 
Continuous Sash 


Moline Forge Co., Rock Island, III. 


Monitor Sash 


Center Pivoted Continuous Sash, with 100% opening, makes the expulsion of gas and smoke an easy matter in this foundry. 


Center Pivoted Continuous Sash is 
particularly desirable in saw-tooth roof 
construction and in monitors of hot 
buildings where maximum outlet for 
smoke and gas is necessary and where 
absolute weathering is not of primary 
importance. 

The sash is pivoted on heavy mal- 
leable iron butts spaced 4’ on centers. 
These butts are attached to the sash 
by steel butt angles riveted to the 
vertical muntins, and to the building 
construction by means of malleable 
iron butt straps bolted in place, as 
shown on page 34. Care should be 
taken to see that the center line of the 
hinge, which is also the center line of 
the sash opening, is 3’’ above the top 
of the structural channel or other 
framing to which the sash is attached. 

The head angle on the sash weathers 
under the building construction at the 
top of the opening, while at the sill the 
long down-standing leg of the movable 
section provides a wide overlap. 

A specially designed weathering cap 
at the end of each run covers the edge 
of the movable section and overlaps 
the end panel building construction as 


the sash closes. This cap is hinged at 
the top to swing outward as the sash 
pivots, as shown in the picture above. 
A guide bracket attached to the sill of 
the sash extends into a guide channel 
under the weathering cap, thus as- 
suring proper alignment. 

Due to its balanced construction, 
the weight of the sash is not borne by 


the operating device, but is supported 
by the structural frame work. The 
sash can therefore be opened and 
closed much more easily and quickly 
than Top Hung Sash and longer runs 
can be operated from each power. 

For operator details, see pages 37 to 
48 under the heading, ‘‘Fenestra Con- 
tinuous Operator.” 


Center Pivoted Continuous Sash used in short runs provides easy operation and 
maximum opening. The weathering caps at the ends of these runs had not yet 
been attached when the picture was taken.

These exterior and interior pictures show an ideal ventilating scheme for “hot buildings.’’ Batteries of furnaces in the center 
of the building discharge a constant cloud of heat, smoke and gases into this exceptionally high monitor. But 9,600 
square feet of Fenestra Continuous Center Pivoted Sash throw the sides of the monitor wide open, while 
the height of the valley roof gives it a chimney action. WindoWalls extending close up 
under the eaves, with ventilators near the sills, keep the lower air pure and provide 
ample daylight, as shown in the view below. 


Interior view of the installation shown above. This gives an idea of the tremendous daylighting and ventilating area 
produced by the Fenestra Center Pivoted Continuous Sash.

Special Types of Monitor Sash 


Monitor Sash 


Designed by the Company’s Engineers 


Plate Mill of the Mark Manufacturing Company, Indiana Harbor, Ind. 


Fenestra Horizontally Rolling Monitor Sash used both in the monitor and in the sidewalls. 


Horizontally Rolling 
Monitor Sash 


In rolling mills, steel mills and other 
structures of this character, Horizon- 
tally Rolling Monitor Sash are some- 
times desired, these buildings being of 
semi-open construction where free and 
continuous circulation of air is all- 
important. 


These sash are of the Fenestra side- 
wall type, fixed light sash being mount- 
ed on substantial rollers and operated 
either by hand or by mechanical 
operators. The usual construction is 
to have the sash alternately movable 
and fixed, the movable units sliding 
past the fixed units to provide a 50% 
monitor opening. Weathering strips 
riveted to the jamb bars provide baffle 
weathering between movable and fixed 
sections. 


The sash as described above are run 
continuously along the monitor, the 
steel details being especially arranged 
for this type of construction. 


Bottom Hung 
Continuous Sash 


Where forging, foundry work or heat 
treating is handled under acomparative- 
ly low roof, the need for rapid changes 
of air becomes imperative. Under 


Bottom Hung Continuous Monitor Sash in saw-tooth roof construction. 
The operating device is in just the reverse position from that occupied when 
used with Top Hung Continuous Sash, the arms pull in from the top in- 
stead of pushing out from the bottom.

North East Station, Kansas City Power & Light Company 


Two runs of Fenestra Tension Operator are used to open and close these unusually large vertically pivoted ventilators. 
Each ventilator is connected to both operators, one at the top and one at the bottom. The lower operator 
is directly connected to the power (shown about half way down the run), while the upper 
operator is handled by means of an auxiliary power as described on page 43. 


such circumstances we sometimes have 
installed continuous sash hung at the 
bottom and opening out at the top. 


Weathering under such conditions is, 
of course, imperfect; but the character 
of the work performed in such a build- 
ing is usually such that slight leakage is 
not important. 

On the other hand, the sash opening 
out from the top provides an outlet 
almost straight upward and creates a 
draft almost like that in a chimney. 
As a means of ridding a wide, low build- 
ing of smoke, heat or gas, it is the most 
practical of all monitor types. 

The question of light should also be 
considered. Monitor sash is usually 
washed infrequently, with the result 
that even when the sash is open the 
amount of light is seriously reduced. 
Top Hung Sash is the worst in this 


respect because it opens the least. 
Center Pivoted Sash, opening wider, lets 
in more light, but Bottom Hung gives 
a clean, wide opening with the sky as 
the limit. 

While the general construction and 
operation of the sash are like that of 
other Fenestra Continuous units, Bot- 
tom Hung Sash is not standard. Special 
angle sections are required at head and 
sill and extra flashing is necessary at 


the head. 

Where sash of this type is desired, we 
suggest that the designer consult with 
our nearest Sales Engineer or write to 
Detroit for suggestions and details. 


Vertically Pivoted 
Monitor Sash 


Vertically pivoted sash, although 


sometimes used in side walls, is adapted 


36 


chiefly for monitors where it may be 
controlled in long runs by means of 
Fenestra Tension Operator. It has an 
advantage in that it may be swung in 
an arc of 180 degrees to take advantage 
of air currents from almost any direc- 
tion. 

This type of sash is not recommended 
where weathering is of first importance, 
inasmuch as the sash, when open, affords 
little protection from driving storms. 
For foundries, and mill buildings its 
use is entirely satisfactory and it has 
been standardized for monitor con- 
struction by some of the largest cor- 
porations of this kind. 


The sash themselves are of the 
Fenestra sidewall type, ventilators 
being pivoted in the center at top and 
bottom. 


nestr 


Operating Devices 


Mechanical Operating Devices 


| fe is not economy to try to adapt one type of 
operator to all designs of sash. For instance: 
In Center Pivoted Sash, the load on the operator is 
greatest at the beginning of the operation and 
least at the end. In Top Hung Continuous Sash, 
the load is least at the beginning of the operation 
and greatest at the end. 


Operator designed for one is not necessarily 
fitted to operate the other. 


Fenestra Operating Devices, therefore, are built 
each for the particular work it is intended to 
perform. Each is guaranteed to perform that 
work satisfactorily. More than that, Fenestra 
operators are built for direct and immediate 
action, easy operation and economy of power. 
Operating arms are designed to give greatest 
leverage at the point where the load is heaviest. 


In offering these devices to the public, therefore, 
we feel that they uphold in every way the integrity 
of design, material and workmanship which has 
always been a Fenestra characteristic. 


Fenestra Operating Devices are of three kinds: 


1—Fenestra Continuous Operator for Fenestra 
Continuous Sash either on the vertical or 
on a slope. 


2—Fenestra Worm and Gear Operator for 
Horizontally Pivoted Sidewall Sash. 


3—Fenestra Tension Operator designed par- 
ticularly for long runs where Pivoted 
Sidewall Sash is used. 


Each of these three types is described in detail 
in the pages following. 


1—Fenestra Continuous Operator 


Specifications 


Mechanical Operator to be of Fenestra Continuous 
or other straight-line type, to be approved by engineers. 
The worm and gear shall be of machine-cut steel, oil 
encased. Worm to be equipped with thrust bearings 
and positive stop. Tension line shall be of 1” wrought 
iron pipe. 

Power to be located near the end of the run, properly 
anchored by means of 14” rods and turnbuckles. An 


Fenestra Continuous Operator is 
designed with four distinct advantages 
in mind. 

1—To open and close the movable 
sections rapidly.

or in sloping planes. 

4—To assure as wide an opening 
as possible. 


Direction of force 


Two basic principles have been em- 
ployed by our engineers, these principles

being exclusive in Fenestra Contin- 
uous Operator design. 


1—Power applied to the sash in

endless chain shall extend downward from the power, 
along the column or wall, to the point of operation. 

Operator arms shall be of steel angles. Tension line 
supports shall be solid steel angles, solidly anchored 
to the building construction and carrying housed rollers 
to support the pipe. 

Operator is to be erected by the manufacturer and 
left in complete working order. 


2—Power increasing faster than 
the load. 

How these principles are utilized is 
best explained by a description of the 
device itself. 

Design 

Fenestra Continuous Operator con- 
sists of a high-grade tool steel worm 
and a worm gear power, oil immersed 
and operated by a chain running over 
a chain wheel on the same shaft as the 
worm. This mechanism transfers a 
pull on the chain through a steel rack 
and pinion to a sliding pipe, which 
operates levers that in turn open the 
sash. 

The levers consist of two arms (AD

and CB), one twice as long as the 
other. The long arm is pivoted to the 
pipe at one end (D) and to the sash 
at the other (A). One end of the 
short arm is pivoted to the center of 
the long arm (B) and the other is 
pivoted to a pipe roller housing (C), 
which is held rigidly to the building. 


The short lever, pivoted at points 
C and B, takes all of the side thrust 
from the long lever, leaving the point 
A to exert a force only in the direction 
of the travel of the sash. The mech- 
anism is really a parallel motion de- 
vice, and as such eliminates so-called 
“motion around the corner’’ and ap- 
plies its power in an absolute straight 
line (CA). 

That the power increases as the mech- 
anism is operated is made evident by 
considering the long lever as a simple 
strut, with the point A resting against 
a wall and lifting a load, while the point 
D rests on the floor. 

If rollers were attached at the points 
A and D, so that they could roll along 
both the wall and floor, it is evident 
that the closer the point D approached 


the wall, or in other words the more 
perpendicular the strut became, the 
easier it would be to lift the load. 
The Fenestra transmission, therefore, 
provides a simple, efficient power line 
free from compounding levers and 
counterweights. It has fewer parts 
than any other steel sash operator on 
the market, with the corresponding 
ease of maintenance and freedom from 
friction. It exerts a direct action on 


the sash in the absolute direction of 
travel, thereby securing maximum 
power with the minimum effort, the 
power increasing faster than the load. 
Any of our engineers or sales repre- 
sentatives will be glad to present 
samples for the criticism of your me- 
chanical engineer or will refer you to 
installations where the durability and 
superiority of our device has been 
thoroughly tested and proved. 


Details of Operator Construction 


The Power 


The Fenestra power consists of a 
worm and gear, both machine cut and 
both protected from dust by an oil- 
filled case. 

The steel gear is provided with 
straight-face, machine-cut teeth and 
extra heavy hub and rim. It fits 
tightly over a 1’ squared solid steel 
shaft, which also drives a pinion i 
mesh with the rack. ; 

Gear and pinion are separated by a 
spacer, and all three are broached out 
to fit over the shaft so tightly and ac- 


curately that they have the reliability of 
a single piece. 

The machine-cut worm and shaft are 
of one piece of high carbon steel of un- 
usual tensile strength. They are turned 
down from one solid bar, and are pro- 
vided with ball thrust bearings to over- 
come friction. The shaft extends 4’ 
beyond the case and is squared at the 
end, to receive the chain wheel, which 
is broached to fit accurately, and is 
held in place by a 14” cut set-screw and 
a cotter-pin. 

Thus, for all practical purposes, the

the solid rolled steel lever arms as described on page 40 and the location of tension line supports described on page 42. 


driving mechanism of this operator is a 
single solid steel unit, absolutely reliable. 


The power case is especially designed 
to provide an unusually long bearing 
surface for the drive shaft. This un- 
usual length is a guard against binding 
and an insurance of easy operation as 
the gear is held absolutely in alignment. 


The operator automatically locks 
the sash in any position, when open. 


The power is not shown in this picture. 


Power Supports 


The power is supported by two wide 
brackets especially designed to with- 
stand great lateral pressure. Each one 
of these is attached to the building 
construction by 14”’ bolts. The outer 
ends of the brackets are trussed with 
1’ tension rods equipped with turn- 
buckles, which insure permanent and 
absolute rigidity. 


The Chain Guard 
The Fenestra Chain Guard is sus- 
pended from the same shaft as the chain 
wheel, between the wheel itself and the 
power case. The chain, therefore, may 
be pulled from any position without 
fear of its jumping from the chain wheel. 


The Rack 
The Rack is in keeping with the care- 
ful design and workmanship of the

the tension line. Slotted punching is 
arranged to provide for slight adjust- 


They are bolted solidly to the building 
construction and carry at their outer 


power, being of high tension solid steel 
of stub-tooth design, machine cut. 


The Tension Line 

The tension line is of 1’ wrought iron 
pipe, supplied in 20’ lengths, with 
junction points reinforced by solid 
steel plugs put in with a drive fit and 
riveted in two directions. 

This tension line, by actual test, will 
support a load of over 15,000 pounds. 

The lever arms are solid rolled steel 
angles, giving maximum strength, and 
are equipped with universal joints at 
all points of attachment. Fittings are 
all designed to reduce friction and give 
easy and free operation. 


The Stop 

In place of the old-fashioned stop 
bars, which halt the movement of the 
tension line without eliminating the 
power, the Fenestra stop is of special 
design, one part being broached to fit 
over the worm shaft at the opposite 
end from the chain wheel. As the 
sash closes, the component part of this 
lock comes into mesh, locking the shaft 
and preventing the worm from func- 
tioning. 

Thus the worm is prevented from 
developing further power and all strain 
on the rest of the mechanism is there- 
fore eliminated. 


Bronze Bushings 
Bronze bushings are used at all 
universal joints.

angles, with the short leg turned down.

How to Determine the Proper Width of Opening 
and Length of Runs 


The real usefulness of any operating 
device depends on its ability to pro- 
vide a sufficient opening rapidly and 
easily under any and all conditions. 

Fenestra Continuous Operator is 
designed to do just that. 

To provide such an operator, the 
manufacturer must, of necessity, de- 
sign it to suit the individual job. He 
must know, for instance, such details 
as these: 


1. Is the sash top hung or center 
pivoted? 

2. Is the sash on the vertical 
or on a slope? 
If on aslope, what is the pitch? 
How high is the sash? 


How long a run is to be oper- 
ated from each power? 

6. What pull on the chain is 
desirable? 


7. Are idlers to be used? 
how many? 


If so, 


Any of these details may be varied 
to meet the needs of the individual 
building. In fact, they are largely a 
matter of selection on the part of the 
builder, and in this selection we are 
always glad to give assistance and ad- 
vice. It must be kept in mind, how- 


40 


ever, that some details must always be 
of more importance than others. 

To say that Fenestra, or any other 
operator, will provide a definite open- 
ing or operate a definite length of run 
without regard to these varying con- 
ditions is to make a statement that 
cannot be other than misleading. 

For example: Two hundred and 
twenty-five feet of Fenestra 3’ high, 
Top Hung Continuous Sash, on a 15° 
slope, can be opened 34” in 24% to 3 
minutes, with an easy pull on the chain; 
but if the same sash were placed on a 
45° slope, or if the sash were 4’ high or 
5’ high, the time of operation would 
have to be longer, or the runs would 
have to be shorter, the pull harder, or 
the width of opening less. 

On the other hand, if Center Pivoted 
Continuous Sash were used, the runs 
could be longer, the width of opening 
greater, the pull easier, and the time 
of operation shorter. 

The length of run to be operated 
from one power is usually determined 
by the type of building and the manu- 
facturing processes it covers. 

Where the building is of considerable 
size and houses only one general type 
of work, it is frequently advisable to 
operate the sash from one power, as 


this saves time and insures uniform 
ventilation throughout. 

But a building may house several 
departments, as, for instance, a foundry 
with a molding floor, a pattern shop 
and a machine shop all under one roof. 
Under these conditions the runs are 
usually operated from several stations, 
as the men on the molding floor might 
want maximum ventilation while pour- 
ing, while the men in the pattern shop 
and machine shop would be most un- 
comfortable in such a draft. For flex- 
ibility in the control of ventilation, 
therefore, short runs are always pref- 
erable. 

Fenestra Continuous Operator will 
solve the problems on any type of in- 
stallation. It will provide wide open- 
ings or operate long runs from a single 
power, and will perform its work with 
more rapidity and greater ease than 
any other operator on the market. 

In operator design, as in sash design, 
it is the aim of Fenestra engineers to 
supply the type of material that will 
give the results desired under the con- 
ditions prevailing. 


Erection 


The Fenestra Construction Company 
erects all Fenestra Continuous Opera- 
tors. This isa highly specialized mech- 
anism, requiring skilled erection, and 
the Detroit Steel Products Company 
is not responsible for its satisfactory 
installation unless it is handled by our 
own Service Department. Branch 
offices are maintained in Detroit, New 
York, Philadelphia, Boston, Chicago, 
Birmingham, and San Francisco for this 
particular service. These offices follow 
shipments, attend to prompt delivery 
of material at the building site, see that 
it is properly installed and, in short, 
take over all the details. 


Details Required with Orders 


To insure an economical and practi- 
cal installation of Fenestra Operator, 
it is necessary that our Engineering 
Department have certain information 
before the order is entered in the shop. 

Floor plans and drawings, showing 
elevations and sections of the buildings, 
are necessary, so that the operator ten- 
sion pipe will not be designed to run 
through wide pilasters, heavy concrete 
or steel columns, gusset plates, etc. 

Structural steel details—that is, shop 
steel drawings—are necessary to show 
where operator supports may be at- 
tached. 

Crane details are necessary, partic- 


a

below under ‘‘Operating Multiple Runs.”’ 


ularly the distance between the columns 
and the crane bridge. This is essential 
in order that the operator may be laid 
out to clear the crane mechanism. 

It is also important that we have the 
distance from the inside face of the sash 
to the inside face of the wall or steel 
work. 

In addition to these details, the an- 
swers to the questions under ‘‘Width of 
Openings and Length of Runs’”’ should 
be determined at the time the order is 
taken. 


Operating Multiple Runs 

Where it is desired to operate several 
runs or banks of continuous sash from 
one power station, a sprocket wheel, 
moving with the main power, is con- 
nected to a similar sprocket, which is 
in mesh with a rack on each of the 
other runs of sash. This auxiliary 
power device is shown in the picture 
at the top of this page. Here, again, 
the width of opening and the length of 
each run is dependent on varying 
conditions as outlined above. 


Special Uses for Fenestra Operators 


The simplicity and direct action of 
Fenestra operating devices make 
them easily adaptable to varying 
conditions. 


The Tension Operator, described on 
pages 53 and 54, has been used suc- 
cessfully with auxiliary powers to 
operate large bays, containing many 
banks of ventilators one above another. 
Vertically pivoted ventilators and 
horizontally rolling sash are easily 
handled by means of Continuous 
Operator or Tension Operator, see 
pages 35 and 36. Fenestra Continuous 


Operator is also adapted to use with 
a somewhat unusual construction, 
where continuous sash are hinged at 
the bottom to open out at the top, 
see pages 35 and 36. This has the ad- 
vantage of providing maximum ventila- 
tion at a point where this is essential, 
but where weathering is of secondary 
consideration. 


The flexibility of the Fenestra tension 
device permits a variety of operator 
designs, in which our engineers are al- 
ways glad to assist without obligation 
to the customer.

Fenestra Electrically Controlled Operator 


Power for Fenestra Continuous Operator, with the electric 
motor attachments. A gear and sprocket replace the chain 
wheel of the manually operated power. 


Fenestra Electrically Controlled 
Operator is designed to open and close 
large areas of Continuous Sash from one 
centrally located station with a mini- 
mum of effort. 

This station may be located at any 
desired point in the building where, by 
pressing a button, the ventilating portion 
of an entire roof or sidewall may be op- 
erated easily and quickly by one man, 

Where ventilation is required over a 
large floor area, it is frequently desir- 
able to centralize the responsibility in 
one person. In such cases, a Fenestra 
Electrically Controlled Operator is ideal. 

One of the best installations is in the 
Government armorplate plant at 
Charleston, W. Va. Other interesting 
installations may be found in the 
National Tube Co., Lorain, Ohio, plant; 
the Bevo plant of the Anheuser-Busch 
Co. and the Commonwealth Steel Com- 
pany in St. Louis, Mo.; the Government 
dirigible balloon hangars at Lakehurst 
and Cape May, N. J.; the General 
Fireproofing Company’s building, at 
Warren, Ohio; the Samson Tractor 
Co., Janesville, Wis.; and the Williams- 
burg Power House in Brooklyn, N. Y.

This largest single room structure in the world is 1,066 feet long, 350 feet wide and 200 feet high. There are more than 100,000 

square feet of Fenestra Steel Windows, with electrically controlled operators. Both sash and operator were designed by the 

Fenestra engineers. The sash are glazed with actinic glass to eliminate the ultra-violet rays which have a deteriorating effect 
upon the balloon fabric. One can realize the size of the building by noting the automobiles in front. 


The limit switch of rugged enclosed 
construction forms an integral part of 
the power unit and is located in a 
convenient position, making all parts 
accessible. The action of this switch 
is positive. It can be adjusted with 
precision to automatically limit the 
movement of the sash in either di- 
rection. 


The push button station is of 
heavy iron construction and is de- 
signed to resist hard usage. The but- 
tons are so arranged and protected that 
they cannot be operated accidently. 


All material, other than that named 
above, and all labor necessary for the 
installation of line switches, fuses, con- 
duit work, wiring, connecting and test- 
ing is to be furnished by others. 


It should be remembered that all 
operator and especially electrically con- 
trolled operator needs occasional in- 
spection, lubrication, etc. The fore- 
sighted builder provides some means 
by which the motors and power stations 
can be reached without undue incon- 
venience. Where ordinary ladders are 
impractical a ‘“‘cat walk’’ or a movable 
platform is sometimes a real economy, 
and is especially useful as an aid to 
window washing.

Mechanical Operator to be of Fenestra Worm and 
Gear design, equipped with thrust bearings. Power 
line to be of 1’’ wrought iron pipe, held in place by 
adjustable steel brackets bolted to the mullions or 
structural steel work. Adjustable rolled steel arms are 


to be provided, one to each ventilator, solidly clamped 
to the power line. Chain or vertical pipe to be carried 
down within easy reach of the floor and provided with 
suitable means of operation. Operator to be erected by 
the manufacturer and left in complete working order. 


Fenestra Worm and Gear Operator 
is a torsion device, designed to operate 
from one power station single or mul- 
tiple rows of Horizontally Pivoted 
Ventilators. 

The power may be placed at the end 
of the run or at any intermediate point, 
but in no case may any ventilator be 
located more than 40’ from the power. 

Where one run of ventilators is to be 
operated, the maximum run on either 
side of the power is limited to 40’ and 
6 standard two-pane high vents. Where 
two runs are to be operated from the 
same station, the maximum run on 
either side of the power is limited to 
20’ and three standard two-pane high 
vents in each run. Where three runs 
are to be operated from the same station,

Design 

A 1” horizontal pipe is held in place 
by substantial rolled steel supports 
attached to the mullions or 
building construction. These 
supports are designed to pro- 
vide for the adjustment of 
the operator, toward or away 
from the sash as desired. To 
the horizontal pipe the venti- 
lator lever arms are attached. 
One armis used for each vent, 
this being attached to the cam 
bracket at the sill of the ven- 
tilator. The pipe is connect- 
ed toa gear, which is operated 
bya machined worm. Power 
is transmitted to the worm, 
either by means of a chain 
operating over a wheel, or by 
means of 1’ vertical pipe 
running down to a miter gear 
provided with a crank within 
easy reach of the floor.

double links, galvanized, and is un- 
usually easy to handle. 


The Fenestra adjustable pipe support is attached to the 
steel sash mullion or building construction and is so 
designed that it holds the torsion line in any 


desired position. 


Erection 


Fenestra Worm and Gear Operator 
is designed as an integral part of Fen- 
estra sash. In erection, before the

such a problem arises, it is perfectly 
feasible to tip the power to any desir- 
able angle, or turn it up-side-down. 
When this is done, the chain is carried 
over idlers to a convenient point of 
operation where it is brought down to 
the floor.

must work freely and, in closing, 
weather at all points. The operating 
device cannot be expected to correct 
distortion of the sash that may occur 


by faulty erection. 


Sometimes Fenestra sash or operator, 
correctly manufactured, is ruined 
through faulty erection. The 
result is an installation alike 
unsatisfactory to the cus- 
tomer and to ourselves. To 
obviate such errors, we offer 
to builders the services of the 
Fenestra Construction Com- 
pany, a subsidiary of the 
Detroit Steel Products Com- 
pany, thereby concentrating 
authority and responsibility 
under one head and insuring 
the erection of Fenestra ma- 
terial in accordance with our 
recommendations. 

The Fenestra Construction 
Company is organized to 
handle the erection of oper- 
ator as well as sash, relieving 
the builder of all details. 
Branch offices are maintained 
in Detroit, New York, Phila- 
delphia, Boston, Chicago, 
Birmingham, and San Fran- 
cisco. These offices are es- 
pecially equipped to follow shipments, 
look after prompt delivery of material 
and see that it is properly installed. 
The Fenestra Construction Company 
guarantees a complete and _ satisfac- 
tory installation. 


Position 


The accompanying diagram shows 
details of powers both inclined and 
inverted. The cross section of the 
building shows a situation where in- 
clined powers are desirable. The ven- 
tilators, on the right side of this narrow 
monitor, could not be seen by a man 
operating them from a station along 
the right hand wall. It is therefore 
much better to tip the powers and 
bring the chains on idlers across the 
monitor and down the opposite wall. 
By this method the person operating 
the mechanism can always see just 
how far the windows have been opened 
or closed. 

At the extreme right in the diagram, 
is a cross section showing how an in- 
verted power allows the chain to 
descend close to the wall, thus escaping 
a traveling crane. Where the power is 
inverted, it is of course necessary to 
attach the lever arms to the top of the 
ventilators instead of to the bottom.

Fenestra Tension Operator is designed 
for use with long runs of Pivoted 
or Reversible Windows. Its chief 
advantages lie in its easy operation 
and in the fact that the number of ven- 
tilators operated from one power is 
practically without limit. 

This is a tension device, consisting 
of a 1” horizontal pipe connected to a 
power similar to that described under 
“Fenestra Continuous Operator.’ 

Channel shaped tension arms, with 
one end clamped to the tension line, are 
attached at the other end to the head 
of the ventilators by means of a uni- 
versal joint. The ventilators are 
opened by pulling in at the top rather

than the usual method of pushing out 
at the bottom. All arms are adjustable 
and, when properly attached, provide 
a 100% opening. 

The operation of the mechanism is 
exceptionally easy and rapid, due to 
the fact that the weight of the venti- 
lators is balanced and carried entirely 
by the sash and the building construc- 
tion. 


Erection 


Many excellent building specialties 
prove unsatisfactory when carelessly 
installed, or when erected by men un- 
familiar with the method intended by 
the manufacturer. To insure that the 


Fenestra operator will give the service 
required, we have organized, as a sub- 
sidiary, the Fenestra Construction 
Company, an organization of trained 
Fenestra service men, who are equipped 
to undertake the erection of Fenestra 
sash and operator under a separate 
contract, relieving the builder of all 
details and guaranteeing the proper 
and satisfactory completion of the job. 

The use of this service places the 
responsibility for a correct installation 
definitely with one concern and insures 
freedom from the difficulties and mis- 
understandings that sometimes arise 
where special material is handled by 
inexpert workmen. 


The power is the same as that shown under 


Arms connecting the head of the ventilators to the tension line pull the 
ventilators in at the top instead of pushing them out at the bottom.

Counterbalanced Windows 


Specifications 


All vertical sliding windows shall be Fenestra solid 
steel counterbalanced type, manufactured by the 
Detroit Steel Products Company, Detroit, Michigan. 

All jambs and mullion sections shall be of solid 
rolled steel I-beam type. Flaring channel guides 
shall be riveted to these sections to provide line 
contact weathering and guides for the sliding units. 

All sliding units shall be held by fittings which will 
permit easy adjustment. Chain shall be of gal- 
vanized flat links and run over roller bearing pulleys. 
All pulley housings shall be attached to the inside 
of the sash frame and easily accessible. 

All Counterbalanced Sash units shall be erected 
and all hardware attached, by the sash contractor. 

After erection and before glazing, all sash should 
receive a final coat of paint by the general con- 
tractor. 

All glazing shall be done under another contract. 

All pointing and grouting shall be done under 
another contract after the erection is completed. 


The pictures show exterior views of two popular types of 
Fenestra Standard Counterbalanced Windows. The use of the 
vertical muntin bars is largely a question of taste and the 
architectural effect that is desired. When closed, the sash are 
weathertight, and when opened, fifty per cent ventilation is 
obtained, heated air escaping through the top and fresh air en- 
tering through the bottom opening.

Counterbalanced Windows 


Advantages of Counterbalanced Windows 


Fenestra Counterbalanced Windows 
are finding increasing favor among 
architects and engineers for use in pub- 
lic buildings, offices, schools, loft build- 
ings and industrial structures of the 
better class, in which it is desired to 
employ a sliding steel window. 

For such buildings, Fenestra Counter- 
balanced Windows have particular ad- 
vantages, namely: 


1—The ventilators slide up and 
down in the way everyone is ac- 
customed to operate a window. 


2—They provide natural ventila- 
tion automatically, since the 


exit for heated air at the top is 
always equal to the inlet for 
fresh air at the bottom. The 
ventilating area is one-half of 
the entire window area. 


3—They are easily washed and 
may be economically equipped 
with roller shades, screens and 
windshields. 


4—They are fire resistant, being 
built of steel sections. 


5—They are manufactured in 
standard sizes, which are more 
economical and can be shipped 
quicker than other sizes. 


Details of Construction 


Particular attention is given to the 
finish and workmanship on Fenestra 
Counterbalanced Sash. The design is 
attractive and the construction is of a 


character that harmonizes with build- | 


ings of the highest architectural finish. 
Where desired, brass weathering is 
supplied at slight additional cost. 


Sections 


To insure easy operation and satis- 
factory weathering, Fenestra has per- 
fected a flaring channel guide which 
is securely riveted to the I-beam jamb 
sections. (See Figs. 1, 2, and 3.) The 
equal leg channels forming the sides of 
the ventilators slide between this flaring 
channel guide and the flanges of the 
I-beam. Two continuous line contacts 
are thus secured, which provide efficient 
weathering. At the same time, the 
sliding sections move easily, since at no 
point does a flat surface slide against 
another flat surface. 

Unequal leg sections at the head and 


sill and interlocking sections at the 
meeting rail provide effective double 
contact at these points. 

Jambs and mullions are of solid rolled 
steel 4” I-beam section. Head and sill 
members are heavy pressed sections, 
especially designed. Sliding units are 
of especially designed solid rolled sec- 
tions and the corners are welded to 
insure rigidity. All sash are carefully 
gone over by hand, to insure a finished 
appearance. 


Brass Weathering 


Brass weathering sections of flaring 
channel design may be inserted at the 
jambs of both upper and lower sliding 
units at slight additional cost. These 
channels are riveted to the I-beam sec- 
tion in such a manner that they are 
entirely covered by the equal leg jamb 
sections of both sliding units. Thus, 
with this construction, both sections 
slide and weather with line contact 
against brass. (See page 57.) 


Fig. 5 


56 


Fittings 


The Pulley is of roller bearing type, adequately “‘housed,”’ 
but not requiring a box effect at the head or a deep shoulder 
in the concrete lintel. This housing also serves as a connection 
between the jambs and the head members, is accessible for 
oiling and easily removed if desired. Specially heavy gal- 
vanized chain, tested to a 400-pound load, connects the upper 
and lower vents. (See page 56, Fig. 1.) 


A nest having the contour of the links of the chain is cored 
into the chain catch. This nest receives three links of chain, 
which fit snugly, thus developing the full strength of the chain 
and eliminating the need for a pin, which is liable to fracture 
the link through which it is inserted. The chain catch on the 
lower vent is adjustable, so that slack, if any, can be readily 
taken up. (See page 56, Fig. 2.) 

A cam action locking device draws the meeting rails together 
tightly, thus adding to the effectiveness of the weathering. 
(See page 56, Fig. 4.) 

The handle or handles, if the sash is wide enough to require 
two, are of a neat, pleasing design and substantial construction. 
They are attached to the bottom rail of the lower sliding sec- 
tion by a bolt and lock nut, which makes it impossible for 
them to work loose, as is frequently the case when hardware 
is tapped on. (See page 56, Fig. 5.) 

When desired, pole operation may be used, as a hole is 
provided for this purpose at the head of the upper unit. 


The adjustable sill clip is slotted, so that the jamb section 
can be moved in either direction to facilitate the erection of 
the sash and insure sufficient clearance for easy operation. 
(See page 56, Fig. 3.) 


Types of Sash 


Standard types of Fenestra Counterbalanced Sash are made 
without horizontal muntins, each pane of glass running from 
head to sill of each sliding unit, no light being more than 24” 
wide or more than 72” high. (See table.) Where desired, 
sash may be designed, using a single pane to each ventilator. 
Where large lights are used, the glass is held in place with 
glazing angles. This is sometimes very desirable in structures 
of the office building type. 


Occasionally, too, we are asked to design the sliding sections 
with small glass lights, using horizontal muntins, so that the 
general appearance of the window will correspond with Fenes- 
tra Sidewall Sash used in other bays of the same elevation. 
Where variations from our standard design are desired, we 
strongly recommend that designers consult one of our repre- 
sentatives, 


Erection 


To give satisfactory service, Counterbalanced Sash must be 
installed with considerable care and set absolutely plumb 
and true. For this reason, all Fenestra sash of this type are 
installed by our own erection organization, the Fenestra 
Construction Company. This company maintains offices in 
Boston, New York, Detroit, Philadelphia, Chicago, San Fran- 
cisco and Birmingham, and from these points covers prac- 
tically the entire United States. 


All sash of this type are shipped ‘‘knocked down,” the 
head, sill and jamb sections being assembled in the field, 
while the sliding sections are shipped assembled and ready 
for erection.

Underwriters’ Windows 


Underwriters’ Labeled Sash 


In about 95 per cent of the industrial 
buildings, ample protection against 
fire is afforded by the use of standard 
Fenestra Solid Steel Windows, espe- 
cially if they are glazed with wire 
glass. 


There are some conditions, however, 
under which the use of a solid steel 


Architects, Mundie & Jensen 


window carrying the label of the Under- 
writers’ Laboratories, Inc., is desirable 
or is required. 


Just what these conditions are can 
best be determined by consultation 
between the owner and his architect 
or contractor, and by careful reading 
of the Underwriters’ specifications 
shown on page 64. 


In appearance, location of ventilators 
and method of installation, Fenestra 
Underwriters’ Windows are identical 
with standard units of Fenestra Solid 
Steel Windows. 


Their use permits the builder to 
secure the same big daylight openings 
in exposures which require a labeled 
sash that he can obtain through the

use of standard Fenestra units in the 
other elevations of his building. 

Any number of units can be com- 
bined by means of the standard Fen- 
estra Solid Rolled Steel T-bar Mullion, 
to fill any width of opening. 

Single units can be built to any 
standard size up to 7 feet by 12 feet, 
either dimension being taken for height 
or width. However, the practical limit 
of ventilated sash is about 60 square 
feet, and of fixed light sash, about 75 
square feet. 

While ventilators may be built up 
to an area of 3000 square inches, the 
practical limitation for Horizontally 
Pivoted ventilators is about 2,300 
square inches and for Reversible ven- 
tilators, 1,344 square inches.

Reversible Ventilator Windows 


nestr 


Reversible Ventilator Windows 


Fenestra Reversible Ventilator Windows are adaptable 
where the characteristics of steel windows harmonize 
with the architecture of the building—and where the 
builder desires an attractive, serviceable window at 
less price than must be paid for hand-made casements 
or special windows of unusual design. 

Because of their slender sections Fenestra Reversible 
Windows provide about 30% more light than wood 
windows of the same size, or, the size of the window 
may be reduced so that the same amount of light is 
secured as in wood windows, thus giving additional wall 
area. For this reason Fenestra windows are particularly 


desirable for offices and other structures where wall areas 
are at a premium, and also for schools where uni-lateral 
lighting is frequently desired and where the ratio of 
light area to floor area is fixed by law. 

It should be remembered that Fenestra is manu- 
factured from slender, durable sections of solid rolled 
steel. Such sections cannot be made to imitate the 
heavy lines usually found in wood windows and orna- 
mental or structural mullions. 

They can be installed however, in ornamental vertical 
and horizontal mullions when such architectural effect is 
desired. In such cases we do not furnish the mullions.

The Framing Member 


The standard framing member used around 
type ‘A’ Fenestra Reversible Ventilator 
Windows is a specially rolled steel channel 
shaped section with unequal legs (shown on 


/IVLLION COVER 


at 
Age i 
4G OPEM/NG DIMENSION 


page 75) known as the 792 Section. It is 
designed to add strength to the frame, afford 
a wide outstanding wing for anchorage in the 
masonry and provide a flat surface for a neat 
plaster finish. 


Dimension Points 


In Fenestra Reversible Ventilator Windows 
of the ‘“‘A”’ type, ‘Sash Dimension” does not 
equal ‘Clear Opening.’ Due to the construc- 
tion of the 792 Section, the sash dimension 
points on this section are taken 14” inside 
the Clear Opening on every side (see pages 
75 and 76). In other words, where 792 Section 
is used, ‘Sash Dimension plus 1’” equals Clear 
Opening.” For the same reason 3’’ must be 
allowed for each mullion when figuring multi- 
ple openings. 


The Ventilator 


The ventilator is balanced with a nice pre- 
cision and opens or closes with unusual ease. 
The swinging end may be projected several 
inches without any appreciable movement at 
the sliding end. Thus, “Swing Out" Ventila- 
tors, opened slightly in stormy weather, afford 
all the protection of top hung windows, while 
‘Swing In” Ventilators, similarly opened, have 
all the advantages of wind guards at the sill. 
Two point weathering is provided at every 
point where the ventilator meets the frame 
while extra long down-standing legs afford 
effective drip at head and sill. 


By tilting the ventilator beyond the hori- 
zontal, both sides of the window may be 
washed from inside the room. 


Arms and Brackets 


The ventilator is supported and balanced 
on two arms of tough spring steel. These 
arms are attached to the ventilator by 
bronze shoulder bolts equipped with bronze 
washers. Connection between the arms and 
the framing members of the ventilator is 


68 


made by means of specially designed mal- 
leable brackets. 


When the ventilator is of the Swing In type, 
the malleable brackets act as alignment stops. 


The 190 Section 


All Fenestra Reversible Ventilators, in both 
Type ‘“‘A”’ and “B" windows are made with 
a specially designed jamb section (No. 190, 
shown below). This provides extra large 
clearances between ventilator and sash, thus 
assuring easy operation without decreasing 
the weathering. It also prevents possibility 
of fouling the masonry when the ventilator 
comes to the jamb. 


Phantom view 
of Bronze Fric- 
tion Shoe 


Bronze Friction Shoes 


Each Reversible Ventilator is equipped 
with two bronze friction shoes, one on either 
side. These are attached to the top rail of 
“Swing Out’ windows and to the bottom 
rail of “Swing In’’ windows and slide verti- 
cally in the frame members at the ventilator 
jambs. They guide the ventilator, insure its 
easy operation, prevent rattle and assist in 
holding the window open at the desired angle. 
They consist of bronze channel shaped shoes, 
mounted on shouldered studs, also of bronze. 


Fig, 3 


Around each stud is an electro-galvanized 
compression spring covered by a _ weather- 
protecting bronze tube. The shoe complete 
is attached by a steel bracket, solidly riveted 
in place, its location accurately gauged to the 
fraction of an inch, thus assuring equal con- 
stant and proper pressure at the jambs. 


Welded Corners 


Ventilators are pivot ended and afterward 
electrically welded at the corners and ground 
down to a smooth and finished surface. Sash 
corners are also pivot ended and welded. 


Alignment Control 


To assist in the uniform alignment of all 
“Swing Out” Ventilators, when open, the 
Fenestra Alignment Control is provided. It 
consists of a spring bronze device, riveted 
inside each guide channel, and so shaped as 
to check the downward travel of the friction 
shoe (Fig. 1). The normal opening of every 
ventilator is, therefore, controlled at an angle 
of about 60 degrees. 

When it is desired to open the ventilator 
farther, slight pressure on the spring releases 
the stop (Fig. 2), and permits the friction shoe 
to slide past (Fig. 3). 

As the ventilator returns to its closed posi- 
tion, the spring action is automatic. 


Combined Units 


Two or more standard windows may be 
combined in the same opening by using the 
standard Fenestra T Bar Mullion. Add the 
sash dimensions of the various units desired; 
and to this sum add 3” for every mullion. 
See page 72. 


Mullion Covers 


Vertical Mullion Covers of pressed steel, as 
shown in the photograph, provide a neat and 
attractive means of covering the mullion 
recess where two or more windows are used 
in the same opening. 

Attachment is made by means of pressed 
metal clips, which are bolted to the mullion 
by the standard Fenestra mullion bolts located 
at the center of each glass light. To these 
clips the mullion covers are attached by bolts 
provided with acorn nuts. 

Where structural steel horizontal mullions 
are used, Horizontal Mullion Covers may be 
employed as shown, to house the steel work 
between the upper and lower windows. 

No other designs of vertical or horizontal 
mullion covers are furnished by Detroit Steel 
Products Co. 

The usual bolts used with our 101 Clips to 
hold the lower window in place are replaced 
by longer bolts, which extend through the 
mullion cover and are fitted with acorn nuts.

Standard Bronze Hardware 


Bronze hardware is supplied as standard 
on all Fenestra Reversible Ventilator Windows 
of the “A “type 

For Swing Out Ventilators within easy 
reach from the floor the only hardware needed 
is the bronze cam handle (Part 114). This is 
a carefully finished fitting of new and pleasing 
design, and is attached to the specially 
designed Z bar bracket, which, in turn, is 
solidly riveted to the sill bar of the ventilator. 
When the window is closed the cam handle 
lies in a horizontal position along the sill. 

A bronze strike plate is riveted to the sash 
at the sill of the ventilator and this carries a 
6’’ bronze stay (Part 122). When the window 
is open farther than 6’’, no stay is used, as the 
balanced construction holds the ventilator in 
position. 

For Swing Out Ventilators beyond reach 
from the floor, pole operation is usually 
desired. A bronze pole ring (Part 151) is 
attached at the head of the ventilator, while 
at the sill the standard bronze cam handle 
and the bronze strike plate without the stay 
are provided. The pole is used to lift the 
cam handle and tilt the ventilator slightly, 
after which a gentle pull on the ring opens 
the ventilator as desired. 

For Swing In Ventilators within reach from 
the floor an automatic latch with bronze 
handle is supplied at the head (Part 112). A 
slight pull on the handle releases the catch 


Part 151 


Part 147 


70 


Part 114 


Part 112 


and allows the ventilator to open inward. 
In closing, the latch works automatically. 

The specially designed bronze spring catch 
(Part 146) with endless chain is used at the 
head of Open In Ventilators, which are 
beyond reach from the floor. These ventila- 
tors are not standard however. 

Part 147 is a spring catch and keeper used 
in Swing In Ventilators within easy reach of 
the floor. 


Glazing 

The standard method of glazing Fenestra 
Reversible Ventilator Type “A” windows is 
with 14” glass, bed puttied, and held in place 
by glazing angles. These angles, mitered 
at the corners, are supplied as standard to- 
gether with brass screws of “barrel” design. 


Underwriters’ Windows 

Reversible Ventilator Windows with “Open 
Out” Ventilators may carry the Underwriters’ 
label, subject to the following conditions: 

No glass light must exceed 350 sq. in 
in area. 

No individual unit must exceed 7’ x 12’, either 
dimension being taken as width or height. 

Special glazing angles and hardware are 
required. 

If Underwriters’ Windows are required 
they must be specified at the time the job 
is estimated. 

Reversible Ventilator Windows of the 
“Open In” type cannot be labeled by the 
Underwriters. 


Part 146 


Reversible Ventilator Windows 


Standard Types and Sizes 


Standard Fenestra Type ‘“‘A’ Reversible Ventilator Windows 
are determined by certain standard ventilator dimensions. The 
accompanying diagrams show the points from which these di- 
mensions are taken. 

As in all steel windows, the ventilator lights which abut on the 
head, jambs or sill of the ventilator are trimmed 1” along the 
abutting edge. 

The standard widths and heights for both Open In and Open 
Out Ventilators are: 


Widths 


28”’ Wide Vent (Open In or Open Out) takes 26’ wide glass 
36’ Wide Vent (Open In or Open Out) takes 34’’ wide glass 


Heights 


12” High Vent (Open In) takes 10” high glass, cut full 
16” High Vent (Open In) takes 14” high glass, cut full 
24”" High Vent (Open Out) takes 22” high glass, cut full 
32” High Vent (Open Out) takes 30” high glass, cut full 


Around these ventilator dimensions is built the entire stand- 
ardization of all Reversible Ventilator Windows. 

Fixed lights are always used at the head of each unit to facili- 
tate shading and permit easy operation of the ventilator. 

Fixed panels are used on either side of the ventilators where 
the width of the window opening is greater than the width of 
the ventilator.

Semi-Standard Windows 


For window openings where the dimensions will not accommo- 
date standard types and sizes, we recommend units of semi- 
standard design. In such units the ventilators and any fixed 
panels used between ventilators remain standard, variations in 
height being taken up in the fixed panel above the upper venti- 
lator, and variations in width being taken up in the fixed panels 
at the sides. 


Intermediate muntins may be had in the ventilators if 
specified when estimate is made.

Special Windows 


Where the ventilators are desired in special dimensions, or 
with other than standard operation, or where a fixed panel 
between ventilators is designed larger or smaller than the 
dimensions shown, the window becomes a special and must 
be laid out in our shop for the individual job for which it is 
required. This work naturally requires more time and can 
only be done at additional expense.

Reversible Ventilator Windows 


Installation Details Type ‘A’ 


How to Use the Table of 
Symmetrical Combinations 


The table of Symmetrical Combinations on 
Page 72 shows Fenestra Reversible Ventilator 
windows used in multiple openings, that is, 
two, three or four individual units used with 
mullions between to fill a single opening. 

The column at the left shows height and 
width dimensions, the width dimensions 
including 3” for each mullion. 

Note particularly that these figures indicate 
Sash Dimensions to which one inch must be 
added to secure the dimensions of the clear 
opening. See Page 68 under “Dimension 
Points.”’ 

Having selected the height and width 
dimensions and from these obtained the 
dimensions of the clear openings, you will 
want to know how many units are required 
per opening. This information is contained 
in the next column to the right, while the 
third column indicates the total number of 
lights. In the extreme right hand column are 
given the number and size of each light in each 
unit. 

For example, suppose you want to fill an 
opening approximately 7’ high by 10’ wide. 
Under Height Dimensions you will find 
6’ 1034” to which 1” must be added, giving a 
standard height of 6’ 1134”. Under widths 
you will find 9’ 984” to which 1” must be 
added making a standard width of 9’ 1034”. 
By making your openings according to these 
dimensions you can use three standard units 
and two standard mullions. Each unit will 
be four panes high, and one pane wide. 


Erection of Fenestra Reversible 
Ventilator Windows 


All Fenestra Reversible Ventilator Windows, 
Type “‘A’’, shown on page 72 must be installed 
by our own erection department, the Fenestra 
Construction Company. This insures a con- 
centration of responsibility, relieves the owner 
and general contractor of much detail and 
guarantees windows will operate satisfactorily. 

To leave the installation of Reversible 
Windows to the general contractor is no 


73 


more logical than to expect him to install an 
elevator. 

It is of the utmost importance that Re- 
versible Windows be set in prepared openings; 
that they be erected true and plumb; that 
clearances be carefully observed and that the 
framing members are not jambed or crowded. 

After installation, the windows should be 
carefully grouted by the mason contractor. 

It is very essential that all ventilators be 
adjusted before glazing and that after glazing, 
the ventilators be locked tight until the putty 
is set. 


Sill Anchor Clips, Part 435-S 


Particular attention should be called to the 
desirability of using Sill Anchor Clips, (Part 
435-S) as shown below under certain conditions 
in almost any type of sill construction. This 
anchor serves to hold the sill solidly in the 
masonry and is of particular value where the 
sash is extremely wide or where a ventilator 
comes directly at the sill. 

Our recommendations are that sill anchors 
be used; First,—in all cases where ventilators 
come to the sill of the sash, regardless of width 
of the sash. (Holes are already punched in 
the sill sections to accommodate these anchors. ) 
Second,—in all cases where the sash is over 
5’ 0” wide, regardless of the location of the 
ventilators. Third,—in all multiple unit 
openings where the mullions are not anchored 
at the sill. 

All Part 435-S clips are supplied without 
extra charge.

Shading and Screening 


Methods of Shading 


To properly shade Fenestra Type ‘‘A” Re- 
versible Ventilator Windows, the shade roller 
should be far enough back from the face of 
the sash so that the shade will clear the 
operating hardware. The minimum distance 
required is 314”. 

We furnish at slight additional cost stand- 
ard shade bracket clips which may be easily 
attached by drilling and tapping two holes in 
the inside leg of the jamb section. These 
clips as shown at the right are slotted to 
accommodate any standard shade bracket, 
these brackets being purchased locally. This 
detail is shown very clearly on page 79. 


Where a kalamein moulding is used as a 
plaster finish around the windows, it is very 
easy to attach any standard shade bracket 
direct to the moulding, as shown in the draw- 
ings at the bottom ofthepage. Cross sections 
of this moulding are shown on page 79. 


Methods of Screening 


We do not make nor furnish screens for 
Fenestra windows, but we will be glad to refer 
those who are interested to competent man- 
ufacturers who make the screening of steel 
windows a specialty. 


On page 79 are shown some suggestions for 


Suggestion for attachment of shade brackets 
when kalamein or other finish moulding is 
used as trim inside Fenestra windows 


78 


Standard Fenestra shade bracket clips (supplied 

as an extra) showing slot to accommodate any 

standard bracket. Shade bracket clips cannot be 

used when Open In Vents come to the head of 
the sash 


screening the various types of Reversible 
Ventilator Windows. Several methods of 
screening are shown, including “roll up” 
screens, vertically and horizontally sliding 
screens, pivoted screens for Open In and Open 
Out Ventilators. The application of these 
suggestions naturally depends upon the type 
of building and the design of windows 
used. 

Note particularly that when screening is 
done on the inside, the screens must be kept 
back at least 314” from the inside face of the 
window in order to clear the hardware. This 
applies also to shades, but where screens and 
shades are both attached, the shade naturally 
must be kept inside the screen. This dimen- 
sion may be reduced in some cases. 


Finish at the Mullions 


While we furnish as an extra, a pressed 
steel mullion cover as shown on pages 69 and 
77, two other suggestions are shown on page 
77. One shows a kalamein mullion cover, 
suitable for use with kalamein moulding at 
the jambs. The other shows a neat finish 
secured by the use of metal lath and 
plaster. Standard Fenestra mullion covers 
are, however, the only ones furnished by 
Detroit Steel Products Co.

Fenestra Type “B” Reversible Ventilator 
Windows meet the frequent demand for a 
Fenestra unit with “‘reversible’’ advantages

intersections by the patented Fenestra joint. 
Glass sizes cares) Yo (12 x18"), and” Z 
(14” x 20”) to harmonize with the glass sizes 
of standard pivoted units. 

The only essential difference between this 
type and standard Horizontally Pivoted 
windows lies in the movement of the ventilator 
which slides down from the top while swinging 
out from the bottom, instead of being pivoted 
near the center. 


Details of Construction 


The Framing Member 

The framing member on all Type “B” 
Reversible Ventilator Windows is our standard 
94 section of solid steel as shown in the detail 
below. The outstanding leg anchors in the 
masonry at head jambs and sill approximately 
one-half inch. 


The sash dimensions of these units are 
always the same as the dimensions of the 


clear masonry opening. In other words the 
dimension points are taken exactly as in 
Horizontally Pivoted sash. Where two or 
more units are used in the same opening, the 


standard Fenestra T-bar mullion is used 
between units, 2” being allowed for the width 
of each mullion. 


The Ventilator 


All standard Type “B” ventilators are of 
“swing out’ design, and are balanced on side 
arms of tough spring steel. Arms, brackets 
and bolts are exactly the same as those used 
in the manufacture of Type “A” Reversible 
Ventilator Windows. Vent corners are pivot 
ended and electrically welded. The ventilator 
meets the sash with a two-point flat contact 
all around the opening thus insuring storm- 
tight weathering. Long down-standing legs 
at head and sill form drips which provide 
additional protection at these points. 

Both the inside and the outside of the win- 
dow may be washed from the inside, by merely 
tilting the ventilator beyond the horizontal.

Extra Clearance at Jambs 

An extra clearance at the jambs is provided 
by the use of our 190 Section as in Type “A” 
windows. This precludes the possibility of 
the ventilator fouling the masonry and insures 
free and easy operation without decreasing 
the weathering. 


Bronze Friction Shoes 

Bronze friction shoes, as used in Type “A” 
windows are attached to the top bar at the 
jambs of all ventilators. These not only 
prevent rattle, but assist in holding the 
ventilator open at the desired angle. In 
addition, they act as ventilator guides and 
increase the ease of operation. 


Alignment Control 

Ventilators are easily held open at a uniform 
angle. This is accomplished by a spring 
bronze device riveted inside each guide chan- 
nel. This stop checks the downward travel 
of the friction shoe and controls the opening 
at an angle of 60 degrees. A slight pressure 
on the spring releases the ventilator and 
permits it to open farther. As it returns to a 
closed position the spring action is automatic. 


Mullion Covers 

Standard Fenestra vertical mullion covers 
may be used with all standard Type “B” 
windows but due to the construction of the 
framing member, horizontal mullion covers 
are not applicable.

Standard Types 

Thirty-six standard types and sizes are 
shown above, each of the types illustrated 
béeingunade in both “Y (2% x18" )and==Z] 
(14” x 20”) glass. “Y"’ widths should always 
be “combined with Y “heights; sandys Ze 
widths with “Z” heights. 

Ventilator lights which abut on the head 
jambs or sill of the ventilator must be trimmed 
1” along the abutting edge. 


Semi-Standard Types 


Although the standard units of Fenestra 
Type “B” Reversible Windows have all 
ventilators opening out, it is possible to secure 
as Semi-Standard, any of the types shown, 
with the lower ventilator made one pane high 
and opening in. Where a one-pane-high 
Opening In Ventilator is desired, it is usually 
better to locate it at the sill, although if the 
sill height is exceptionally low, it may be 
placed one pane up. 

Either of two types of opening in ventilators 
may be used. The standard Reversible type 
is constructed exactly like those described on 
page 68. If desired, however, the ventilator 
may be pivoted 34” from the bottom to open 
in from the top. 


Part 146 


1 


Part 147 


When this is specified, the friction shoes are 
omitted and the ventilator opening is limited 
by concealed side arms. 


Shading 

The best method of shading Type ““B” 
Fenestra Reversible Ventilator Windows is 
by attaching the shade brackets directly to 


the building construction. (See drawings at 
bottom of page 78.) Due to the construction 
of the 94 Section, it is not easy to utilize the 
standard Fenestra shade bracket clip shown 
on page 78. 


Screening 

The suggestions for screening that are shown 
on pages 77 and 79 apply equally well to the 
types of Reversible Ventilator Windows on 
page 82. We do not make nor supply 
screens but are glad to refer those who are 
interested to companies who make the screen- 
ing of steel windows a specialty. 


Erection 

All Fenestra Reversible Ventilator Windows 
of the type shown on page 82, must be 
installed by the Fenestra Construction Com- 
pany, which is a subsidiary of the Detroit 
Steel Products Company. The men employed 
by this organization are all expert steel sash 
erectors and are equipped to install our 


Reversible Ventilator Windows 


Part 151 


Part 150 


products with much greater speed and accu- 
racy than any general contractor, no matter 
how conversant he may be with this type of 
window construction. 


Standard Iron Hardware 


Iron Hardware is supplied as standard on 
all standard Type “B” Fenestra Reversible 
Ventilator Windows. 

For Swing Out Ventilators within reach of 
the floor, the cam handle, Part 150, is sup- 
plied attached to the Z bar bracket, which is 
riveted to the sill of the ventilator. Swing 
Out Ventilators out of reach from the floor 
are provided with cam handle at the sill, and 
pole ring (Part 151) at the head. 

For Swing In Ventilators, within easy reach, 
a spring catch and keeper are provided at the 
head. of the.wventilators .(Part 147.) 2 Phe 
catch has a short handle in which is a finger- 
sized hole for ease of operation. A slight pull 
releases the catch and allows the ventilator to 
open inward. 

A specially designed spring catch with end- 
less chain, (Part 146) is used with Swing In 
Ventilators out of reach from the floor. These 
windows are not standard however. 

Where desired, bronze cam handle and 
bronze pole ring may be secured for Type “B” 
ventilators at slight additional cost.

For Educational Buildings 


The increasing popularity of 
Fenestra Steel WindoWalls for 
school buildings is based on sev - 
eral factors. 

1—The cost of wood is con- 
stantly advancing and Fenestra 
eliminates not only the cumber- 
some wood sash and frame but 
also the trim around the win- 
dows. 

2—Fenestra's exceptionally 
large glass area, and slender 
steel muntins make it possible 
to secure 30% more light than 
can be secured with wooden 
windows. This helps the archi- 
tect maintain his ratio of window 
area to floor area and still pre- 
serve sufficient masonry for 
architectural effects. 

3—The fireproof qualities of 
steel are an unquestioned ad- 
vantage. 

4—Ventilation is more easily 
secured and controlled by Fen- 
estra windows which do not 


warp nor stick—always operate 
se Se Architects, Perkins, Fellows & Hamilton Contractors, The H. G. Christman Co. 


5—Although experiments Model High School, Ann Arbor Michigan 


show that shadows thrown on ‘ 
the desks by mullions, muntins, meeting rails and so the narrow steel members of Fenestra windows nat- 
on, theoretically at least, are not a vital consideration, urally eliminate such objections.

The Jackson Building, Asheville, North Carolina, 
will be the first fireproof office building in the western 
part of the state. It is to be 14 stories high, 204 feet. 

Mr. L. B. Jackson writes: 

“We are glad to state that we purchased Fenestra 
Reversible Windows for this building after due con- 
sideration and a thorough investigation of all the differ- 
ent types of windows that are now on the market. 
We believe that the type of windows selected by us 
gives our tenants better control of ventilation. Another 
reason we selected Fenestra is because of the fact that 
the bottom ventilator is hinged to act as a wind shield, 
this being a very important feature in office buildings. 

“We appreciate the co-operation that your repre- 
sentative has given us and feel sure the windows will 
prove satisfactory in every way.”

For Hotels 


The ruffled curtains and small glass 
lights add a very “homey’’ atmosphere 
to the otherwise typical hotel bed- 
room of the Hotel Rennas, Shamokin, 
Pa. Fenestra Reversible Ventilators 
projecting entirely outside the room 
make possible this very attractive 
treatment of the window opening. One 
gets an impression of lightness and 
airiness even with the upper venti- 
lator closed, due largely to the elimina- 
tion of wood trim while the plaster 
finish is carried directly to the window 
frame. By reversing the ventilators 
the window washer cleans both sides of 
the glass from the inside. 


For Banks 


The window treatment employed in 
the Peoples State Bank, Astoria, IIl., 
is typical of present day bank construc- 
tion. The building is of classical 
colonial design, the long slender mun- 
tins of the windows enhancing the 
appearance of height while the cam- 
bered heads add to the monumental 
dignity of the building. The height of 
the windows assures an abundance of 
daylight in the banking rooms. The 
sash is reversible and since the ven- 
tilators project outward, there is no 
obstruction to interfere with shading. 
Natural ventilation is secured by open- 
ing the lower ventilators to admit fresh 
air, while vitiated air escapes through 
the opened upper ventilator.

Camber and Semicircular Windows 


Windows of Unusual Design 


Camber Head and Circular Head Windows 


Modern industrial builders tend to- 
ward the use of square headed window 
openings, rather than the camber and 
semicircle heads so popular some years 
ago. 


On the other hand, the attractive 
appearance of the arched head is self- 
evident, and in brick buildings it some- 
times saves the cost of steel lintels. 
Where economy is an important item, 
it is not unusual to fill segment head 
openings with Fenestra 12-gauge steel 
filler plates bolted to the head of 
standard square head Fenestra sash. 


Architects, Bakewell & Browne 


Standard Fenestra Types 

Where cambered or semicircular sash 
are desired, they may be secured in 
any of the standard Fenestra designs 
and dimensions shown on the following 
pages. 

In designating camber heads, the 
letter C is used preceding the glass size 


Y or Z, and the figure following the 
glass size gives the number of lights 


In designating semicircular 


heads, the letter S is used before the 
glass size Y or Z, and the figure follow- 
ing the glass size indicates the number 
of lights wide. 

Where a semicircular head is used

Camber and Semicircular Windows 


Designed and erected by City Engineers 


Auxiliary Power House, City Light Plant, Seattle, Wash. 
Each bay in this power house is 30 feet high and 10 feet wide, 
composed of nine standard units. The built-on camber 
head makes the upper units of each bay a special type. 


with horizontal structural mullions 
above several combined square head 
sash, the number of lights in the width 
of each unit is also designated. Thus 
an “S Z 10-343’ indicates a semicir- 
cular head, with 14’ x 20” glass, 10 
lights wide, used above three units of 
square head sash, these units being 
respectively 3 lights, 4 lights and 3 
lights in width. 


Note particularly the four dimen- 
sions shown under each of the standard 
types of camber heads on the opposite 
page. ‘“S D” means ‘Sash Dimen- 
sion;” ‘“‘H”’ means ‘‘Height from sill to 
center of arch;’ ‘‘A’”’ means “Arch,” 
or the distance from the sides of the 
arch to the sill; and ‘‘R’’ means 
“Radius” of the camber. These dimen- 
sions must always accompany orders 
for camber heads. In semicircular 
heads the ‘‘H” and “R’”’ dimensions 
are naturally identical, while the ‘‘A”’ 
dimension is eliminated. 


Details of Construction

mullion is used below. 

Where it is desirable to use separate 
semicircular heads of a greater width

Power House Sash 


Fenestra Power House Sash 


Long experience leads us to 
believe that especially designed 
sash for power houses is usually 
unnecessary, and it naturally 
means an increased cost to the 
purchaser. 

Out of several hundred power 
houses that we have equipped 
with steel WindoWalls, approxi- 
mately 90% have installed Fen- 
estra standard units. These can 
be built with all lights fixed, as is 
sometimes desired in turbine-

Advantages to Home Owners and Builders 


To Home Owners 


They admit, on an average, 80% more light than wood 
windows of exactly the same size. 


They are made from solid rolled steel sections that never 
warp nor stick—always open and close easily. 


When open, they admit more air—thus providing better 
ventilation. 


They provide better protection against weather because 
they shut tight with a two-point flat contact—never 
rattle. 


Being made of solid rolled open hearth steel, they are 
non-inflammable and fire-resisting. 


They last longer and look better than wood windows— 
never split, splinter, nor decay. 


They are very easy to screen, screw holes being provided 
for that purpose. 


Being of steel, they discourage prowlers and form a pro- 
tection against rodents which sometimes gnaw through 
wood windows.

To Builders 


They come assembled—sash, frame and hardware all 
ready to install. 

Jambs and sill are in one continuous piece making the 
frame absolutely rigid. 

By removing two cotter pins, the sash may be taken out 
of the frame, and their accurate manufacture makes 
them interchangeable. 

They are less bulky than wood windows, and, therefore, 
much easier to handle. 

They are adaptable to any type of construction—as easy 
to set in poured concrete or concrete block as in brick. 

The mason does the entire work of installation—wood 
windows require the work of a mason, a carpenter anda 
painter. 

They save time—an experienced mason can install a 
steel window quicker than a wooden one. 

They are already painted—one priming coat—before 
they are shipped from the factory. 

They are for sale by local dealers who carry them in 
stock for immediate delivery. 

With all their advantages, their cost is surprisingly low.

Basement Windows Sold Exclusively Through Dealer 


In localities where dealers have been appointed, 
Fenestra Basement Windows are sold exclusively 
through them. Hundreds of dealers in all parts 
of the country carry these windows in stock 
ready for immediate delivery. Any responsible 
dealer can secure these windows by writing to 


Detroit Steel Products Company, 2250 East Grand 
Boulevard, Detroit. In localities where no dealers 
have been appointed and where the builder or 
home owner wishes to deal with us direct, we 


shall be glad to quote prices. 


Details of Construction 


Hinges are large, easily 
accessible and have re- 
movable hinge pins. Sash 
can be glazed and installed 
after frames are in place. 


Self-centering wedge lock 

which insures that win- 

dow will close and seat 

properly and be free from 
rattles. 


Absolute anchorage and air- and 
water-tight weathering at the jambs 
are obtained by means of the fin which 
projects into the masonry. 

The flare in front of the fin provides a 
guide for the brick layer, and gives a 
neat finish similar to a brick mould. 

The leg at the back of the fin serves 
as a line guide to the mason in laying 
up the inside of the wall, and prevents 
the sash from being fouled. 


Weather Tight Head Connection 


The upstanding leg of the casement 
head section projects up back of the 
lintel assuring weatherproof anchorage 
in the building. Please note also the 
two point flat contact between sash 
and frame. 


The Drip Keeps Water Out 


At the sill, where special protection 
from driving rain is required, the front 
leg of the channel forming the sill of the 
sash is turned out and down, forming a 
drip, which keeps the water out. This 
feature, in addition to the double con- 
tact weathering between sash and 
frame, and the imbedded leg of the 
frame member makes the sill weather- 
proof. 


A Three Purpose Locking Device 


To draw the weathering members 
on sash and frame tightly together; 
to provide a simple and effective means 
of securing the sash when closed, and 
to furnish a convenient method of 
holding it open,—this is the triple

purpose of the self centering lock used on Fenestra base- 
ment windows. 

The lock itself is a heavy wedge, attached to a sturdy 
ring on a strong chain, riveted to the sill member of the 
sash. 

A tapered and slotted tongue is attached to the sill 
member of the frame. The sill member of the sash is 
notched to ride over this tongue so that as the sash closes, 
it is automatically brought to center. The wedge slips 
into the slot, bringing the weathering tightly into contact 
and locking the window. 

This self centering feature is important since it insures 
that the sash will seat accurately. 

The sash is hung on butts, which are accurately located 
and stoutly riveted to the sash and frame. 

The split hinge pins can be slipped out, and the sash 
removed for glazing, either before or after the windows 
have been delivered to the job.

Basement Windows 


and Sizes 


This size works out well 
with concrete block construc- 
tion, fitting an opening two 
blocks wide and three blocks 
high with a trowel finished 
sill. 


For houses with low grade 
lines, we recommend this 
size, which provides 150% 
more daylight than a wooden 
window to fill the same sized 
masonry opening. 


This three light window, 
taking 12 by 18 inch glass is 
very popular. It works out 
well with either brick or con- 
crete block and is the one 
most used in the average 
type of construction. 


This size works out par- 
ticularly well with the 24 
inch concrete block in use in 
some sections of the country. 
The sash is equal to one and 
a half blocks in width and to 
four blocks in height, with 
a sill.

In Brick 


The channel and fin construction of the Fenestra jamb 
member provides a guide for the mason in laying up 
both the inside and the outside courses of brick, the 
outstanding fin providing secure anchorage. With the 
brick work true and plumb behind these guides there 
is no chance of binding the sash and preventing it from 
opening. The sill may be of cast stone, cut stone, poured 
concrete, brick, or other material, set so that the down- 
standing leg of the frame is behind it. The sill may then 
be finished on the inside with any of the common methods.

The 3 light 12” x 18” can also be 
used with concrete block accommo- 
dating 214 blocks in width with three 
blocks in height, with a 4” stone or 
cast sill. 

The 3 light 11” x 24” works out with 
24” blocks, accommodating one and 
one half blocks in width and four blocks 
in height with a 4” stone or cast sill. 

Block machine manufacturers are 
now providing end gates for casting 
slotted end blocks similar to the 
detail shown above. Many block mak- 
ers are carrying these blocks in stock. 
The slot is filled with mortar before 
the block is set in position. Where 
slotted end blocks are not obtainable, 
blocks with concave ends are em- 
ployed, the outstanding fin at the 
jamb of the sash extending well into 
the cavity which is grouted flush. Be 
sure to wet the block before grouting. 

Any type of sill construction may 
be employed. 


In Poured Concrete 
When the basement is to be of 


poured concrete, it is customary to 
provide a prepared opening to re- 
ceive the sash, similar to that shown 
in the detail above. This rebate is 
made by nailing a strip to the inside 
of the form at the jamb. When the 
form is removed, the sash is slid into 
the rebate thus left, and grouted in, 
with the flaring edge tight against the 
front of the rebate. 

Sometimes, the form is built against 
the fin, with proper allowances not to 
foul the sash. The wall is then poured 
with the window in place. 

Usual methods of sill construction 
are employed.

The fin member at the jambs, and 
the angle at top and bottom make this 
type of installation easy. 

The detail drawings above show the 
methods of attaching the frame of 
the sash to the woodwork. 

Masonry sills are usually used, al- 
though wood can be used as shown. 


In Tile and Field Stone 
Anchor clips 8” long are supplied 
without extra charge—four for each

General Utility Window 


A New Steel Window 
for Small Buildings 


The new Fenestra Utility 
Window is specially designed for 
small buildings such as private 
garages, filling stations, shops, 
stores, and basements high above 
the grade; also for barns, gran- 
aries, implement sheds, poultry 
and hog houses. 

It embodies all the advantages 
of steel window construction, 
more light and ventilation, 
greater ease of operation, protec- 
tion against fire, and security 
against intrusion, and in addi- 
tion, offers surprising economy 
and ease of installation. 

The window is made from 
standard Fenestra solid rolled 
steel bars. It comes in only one 
size—3’414" wide by 3/714” high 
with 1%” extra outside these 
dimensions for anchorage in the 
building. The sash, or ventilator, 
is 22” high pivoted 2” above 
center and provided with a stay 
bar which permits 20, 40 or 60

degree opening. At the same 
time the sash does not project 
far enough either inside or out- 
side, to be in the way. 

When the sash is closed the 
cam locking device falls into 
place securing the window auto- 


matically while the weathering 
makes a two-point flat contact 
all around. All windows are 
given one dip coat of red mineral 
paint before shipment but should 
be painted a second coat after 
installation. 


Distribution is made exclu- 
sively through dealers whose 
stocks are supplied from a score 
of convenient warehouses. 

You will find this window 
attractive, easy working and 
moderately priced. 


Construction Details 


Details of the Fenestra Utility Window and 
methods of installing are shown at the right. 

The column at the left shows installation in 
concrete block, the upper sketch showing the 
window with a poured concrete lintel and sill. 
Note that it fits exactly in a space 244 blocks wide 
by 6 blocks high (this dimension including the sill). 

The head detail shows the necessary rebate left 
in the lintel into which the projecting leg of the 
window frame is inserted and grouted. This rebate 
is usually made by nailing a wood strip inside the 
form before the lintel is poured. 


The sill detail shows the window as it would look 
set on either a poured concrete sill or a precast sill. 


The jamb detail at the bottom, shows an installa- 
tion in a slotted end concrete block. These are now 
furnished by most block makers for steel windows. 
The common block with concave end may be 
satisfactorily used. 


The column at the right shows the window 
installed in wood. Here the opening should be 
made a little larger than the overall dimensions of 
the window. The head detail shows the projecting 
leg set against a wood strip with the casing brought 
down on the outside to hold it in place. The sill 
detail shows the use of wood screws to hold the 
window, countersunk holes in the frame being 
provided for that purpose. At the jamb the window 
is held in position both by the siding and the casing. 

The Utility window requires only two sizes of 
glass, four lights 12” x 20” and two lights 13” x 20”. 
The windows are first bed puttied, then the glass is 
inserted and held with glazing clips and the face 
putty is applied. Clips, cam handle and stay bar 
are wired to each window for shipment. 

The new Fenestra Utility Window is designed to 
permit easy and economical installation. Below are 
some installation features of particular interest to 
architects, contractors and builders. 

It is adapted to all standard types of construc- 
tion—brick, tile, concrete block, poured concrete, 
stucco and frame. 

Over-all dimensions fit concrete block—2'4 


blocks wide and 6 blocks high, including sill. 
Comes complete—frame, sash, hardware, and a 


priming coat of paint. 

Projecting fin at jamb imbeds into masonry, 
forming a wind-proof, weather-tight anchorage. 

In brick construction two guides at each side of 
jamb fin enable mason to lay up both inside and 
outside courses without danger of fouling sash. 

Carried in stock by local dealer for immediate 
delivery.

| Swinging and Sliding Doors 


Fenestra Steel Doors are of two general types, Swinging and Sliding. Each of these types is, in turn, made 
in “Channel” and “Tubular” design, and to fit single or double door openings. Orders should always give 
accurate dimensions of the door openings. The width dimension is measured from back to back of door 
frames. For the height, the dimension is measured from back of overhead channel to finished floor line. 


Atypical installation of a Fenestra standard single swing door, 
used in combination with standard Fenestra Sidewall Sash 
units. Notice the door opening isentirely ‘“‘ bricked in.” 


E 


Here is a pair of Fenestra standard double swing doors. 
High steel kick plates, heavy hardware and rigid con- 
struction make them practically indestructible. 


Fenestra Swinging Doors 


Fenestra single swinging and double 
swinging doors are manufactured in 
two types: 

1—Steel Channel Trim Doors. 
2—Steel Tubular Doors. 

These types are limited in width and 
area as indicated on page 107. 


1—Channel Trim Doors 


Channel Trim Doors are made from 
heavy rolled, solid steel, U shaped chan- 
nels butted together over solid corner 
castings, through riveted, with counter- 
sunk rivets, to insure perfect rigidity. 


Lower panels are provided with steel . 


kick plates to a height of about 4’, the 


upper panels being glazed. Glazing 
angles are furnished as standard and 
4"' wire glass should be used. 
Standard Fenestra latches or locks, 
butts and weathering plates are pro- 
vided where needed. Special hardware, 
such as door checks or anti-panic hard- 
ware, may be had at additional cost. 


2—Tubular Doors 


Tubular doors are made from heavy 
rectangular steel tubes, mitered and 
welded at the corners. 

Kick plates and standard Fenestra 
hardware are supplied as in channel 
doors.

Semi-Standards 


Where it is necessary to design open- 
ings for either channel or tubular doors 
in dimensions other than the standard, 
multiple of 6’, try to make use of 
2” dimensions, (for example, 3’ 8’’ x 8’

Erection 


Installation of swinging or sliding 
steel doors is an undertaking that 
should not be handled by a novice. 
Steel doors are not like wood doors 
which can be planed to fit. It is ab- 
solutely necessary that steel door 
frames be accurately made and that 
the doors be hung plumb and true. 


Our Service Department, The Fen- 
estra Construction Company, is com- 
posed of men who have had long 
experience in erecting both steel sash 
and steel doors of various designs, 
and we strongly recommend that the 
customer avail himself of this service.

How to Designate Swinging Doors 


It is very necessary that all orders for swinging doors should include information 
as to how the doors are to be hung and which way they are to swing. Unless 
specifically informed otherwise, we always designate a swinging door as a “‘left open 
in door,” “right open in door,” ‘left open out door,” or “right open out door,” 
in accordance with the diagrams shown on this page. 

The “outside” of an outside door is naturally the one exposed to the weather. 
Where interior doors open from hallway, the hall side is always considered the 
outside. Where interior doors connect two rooms, a rough sketch, showing which 
is to be considered the outside, should accompany the order. 


Fenestra Channel Door Frames 


We strongly recommend that all 
door frames be purchased locally, as 
they should, in all cases, be installed 
when the building walls are erected, so 
that they may be properly anchored. 
Steel sash and doors, on the contrary, 
should not be installed until the build- 
ing walls are practically completed. 
We will be glad to furnish drawings, 
showing details and dimensions of door 
frames, on request. 


Particular care should be used to see 
that frames are made to exact dimen- 
sions and erected plumb and true and 
solidly anchored. 


Where doors are surmounted by 
transoms or flanked by steel windows 
we strongly recommend that the build- 
ing construction be carried between the 
door frame and the frames of the win- 
dows as shown on page 105. 


Where the customer particularly de- 
sires that we supply door frames,’ we 
furnish, at extra cost, frames of 4’, 
6”, or 8” channel, in accordance with 
standard types 1, 2 and 3 shown on 
this page. 

Types 1 or 2 are preferable as the 
frames may be installed with the walls 
and the doors may be shipped later 
with the windows which should be in- 
stalled in prepared openings.

Channel frames for Sliding Doors may be used in almost any depth desired as they are not 
required to carry the load of the door. Where Swinging Doors are used, however, we recommend 
the following depth of channel frames as satisfactory. Larger channels may of course be used for 
the protection of walls or for structural purposes.

Fenestra Sliding Doors 


Typical installation of Fenestra Horizontally Sliding Double Doors 


Fenestra single sliding and double 
sliding doors are made in both channel 
and tubular types. 


They are similar in detail to swinging 
dcors of channel and tubular design 
but are equipped with standard Fen- 
estra sliding door locks or latches, as 
the case may be, and with proper tracks 
and hangers. Special hardware may 
be secured at additional cost. 


Specifications should always give the 
accurate dimensions of door openings. 
See top of page 105. 

Fenestra Sliding Doors are limited 
in width and area as shown in the 
illustrations on page 110. 


Standard Sizes 


Widths and heights of Sliding Doors 
have been standardized as shown 
below. These types can be supplied 
quicker and usually at less expense 
than doors that are not standard.

Where it is necessary to design doors 
in dimensions other than standard, 
try to make the width and the height 
some multiple of 6”. If it is impossible 
to design a door opening in multiples of 
6”, then it should be designed in mul- 
tiples of 2’. Odd inch dimensions are 


not desirable and fractional inch 
dimensions should never be used. 


Where one dimension is special it is 
very desirable to keep the other dimen- 
sion standard if possible. 


Guide slot at sill of sliding door 


Each Fenestra sliding door has at the 
bottom a steel plate projecting down- 
ward into a slot in the floor, through 
which it slides when the door is oper- 
ated. This construction serves two 
purposes. First, it acts as a guide to 
keep the door in alignment when it is 
opened or closed. Second, the plate, 
fitting into the slot, serves as a 
weathering member between the bot- 
tom of the door and the floor. As a 
rule, the slot is formed by placing two 
angles back to back in the floor with a 
space between them wide enough to 
accommodate the plate. These angles 
are not supplied by the Detroit Steel 
Products Company.

Interchangeable Partitions 


Interchangeable Partitions 


Fenestra Interchangeable Partitions 


are designed for use in warehouses, 
factories, mills, garages and the office 
portions of industrial buildings. 

They are manufactured from mould- 
ed sections of solid, rolled steel with 
doors of heavy U shaped channel, and 
mullions and door frames of 16 gauge 
formed steel plate. The framing 
member around each unit is an equal 
leg solid rolled steel channel shaped 
section. 

Base plates of 14 gauge steel are 
inserted between muntins to a height 
of 36’.. The upper portions should be 
filled with 144” clear or opaque glass. 
Glass and base plates in the doors are 
held by glazing angles. In the fixed 
sections, spring clips and putty are 
satisfactory. 


Laying Out A Partition 


Never, under any circumstances 
figure on a combination of partition 
units that will exactly fill an opening 
between columns. Always try to run 
the partition on one side of the col- 
umns or the other, or if it must go be- 
tween columns allow several inches at 
each end for filler plates or plaster. 
This is absolutely necessary to take 
care of inaccuracies in building con- 
struction and to allow for radiators, 
bases, window sills etc. For the 
same reason never figure on a parti- 
tion unit coming tight against the 
ceiling. Let the mullions run up to 
the ceiling but keep the partition 
units down. The intervening space 
is necessary to allow for column caps, 
sprinkler pipes, fixtures, etc., and 
may be left open entirely, or filler 
plates may be fitted around the 
obstructions. Sometimes it is feasible 
to use metal lath and plaster, but this 
work is not handled by Detroit Steel 
Products Company. 

First determine the total length of 
the partition. Let’s assume it is 125’. 
Next establish your mullion centers 
repeating the same units as far as 
possible so that your mullions will be 
spaced symmetrically. 

You will want to use the 4-light wide 


Diagram of Interchangeable Units.

units if possible (see page 112) as the 
larger the unit the fewer the units and 
mullions needed, and the lower the cost. 
Take the Unit Dimension (which is the 
center to center dimension—6/43%”’) 
and you will find 19 of them (either 
fixed light or with doors) will fill 120’ 
114%". You will therefore have 4’ 
0%" over. You can insert a 2-light 
wide filler panel which will be 3’ 154” 
wide and the remaining 1114”’ should 
be filled with filler plate. 


Interchangeability 
By loosening two mullions any three 


111 


light or four light wide unit may be 
removed without disturbing the rest 


of the partition. Units containing 
doors may be inserted in place of fixed 
units, or vice versa. For example if a 
door were suddenly needed in the 
fixed portion of a partition already in 
place, a standard unit could be re- 
moved, and a unit of exactly the same 
size, but containing a door, could be 
purchased and slipped into place.

type is made in three different heights 
and two different widths as shown on 
this page. Filler panels ‘‘A” and “B”’ 
are made in heights corresponding to 
the interchangeable units. 

Units which include doors are 
shipped knocked down,—that is, with 
the door, the door frame, the mullion, 
the fixed side panel and the transom 
sash, if any, allseparate. In assembling 
such a unit, the door must always be 
hung from the mullion, which is re- 
inforced to receive the butt screws, 
but the side panel may be used on 
either side of the door. 

The two light wide side panel ‘“‘B”’ is 
not interchangeable with the two light 
wide door. 

In laying out a partition, remember 
that 2’’ must be allowed for each mul- 
lion and that partitions require a mul- 
lion at each end. Thus, a partition 
composed of three units would require 
four mullions.

Corridor Windows 


Fenestra Corridor Windows 


Fenestra Corridor Windows answer

creasing the popularity of small offices

and filing cabinets, storage closets and

therefore is to build the partitions solid ‘ S

Fenestra Corridor Windows are ideal 
for this purpose. Standard types are 
made in 2-light wide fixed, 3-light wide

type is made in three glass sizes—20” x

Five Fold Responsibility 


The Detroit Steel Products has considerably more to sell than just ‘Steel 
WindoWalls.”’ We prefer to sell, instead, ‘‘satisfactory window installa- 


99 


tions. 


Steel windows must be designed 
like an automobile or a typewriter to 
give the service the customer expects. 
That is part of any well made product. 
But after that, there are at least five 
other points in which steel windows are 
unique: 


1—They must be laid out proper- 
ly in the architect’s plans to 
produce the desired results 
with maximum economy. 


2—They must be estimated 
correctly for each individual 
operation, to give the con- 
tractor accurate figures for 
use in making up his bid. 

3—They must be detailed accu- 
rately so the architect can be 
sure they will fit properly with 
other materials. 


4—They must be delivered when 
needed, because a delay may 
retard the entire building. 


5—They must be properly erected 
because only when they are 
in a wall does their real service 
become apparent. 


Fenestra recognizes and assumes 
this five-fold obligation. 


Fenestra Design 

Fenestra design does not need elabo- 
ration. As the makers of the first steel 
windows in America, and as pioneers in 
most of the improvements in steel sash 
since that time, we feel that our broad 
experience and engineering skill are 
reflected in a product which always has 
been and still is recognized as the 
standard. 


Fenestra Layout 
Every Fenestra representative is 
thoroughly equipped to advise with 
architects and engineers as to the most 


efficient window layout for his particu- 
lar building. We welcome requests for 
assistance of this kind, and give it 
promptly, absolutely without charge 
or obligation. 


Fenestra Estimating 


Every Fenestra Sales Office is 
equipped to give quick and accurate 
estimates on windows for practically 
any type of building. Local Detail 
Departments in all Branch and Dis- 
trict Offices handle rough sketches and 
details and co-operate with the Sales 
Department to give a double check on 
the accuracy of all figures. 


Fenestra Detailing 


We make detail drawings on almost 
every large operation and submit them 
to the building designer for his check- 
ing and approval. This is work that 
calls for close co-operation between the 
material maker and the architect, en- 
gineer or contractor. Almost in- 
variably, changes are desired on one 
side or the other—plans must be 
checked—dimensions O. K.’d. Every 
step carries the possibility of misunder- 
standing and delay. 


To insure prompt and _ intelligent 
service, all work of this kind is handled 
by Fenestra through Branch Office and 
District Office Detail Departments, 
especially maintained for this purpose. 
They have authority to settle details 
without reference to the Home Office. 


No orders are accepted at the factory 
until approved by the Head of the 
Detail Department in the territory 
from which they come. 

The advantages of this plan are 
numerous: 


It assures the building designer that he has a 
man near him who understands his work, and 


There is a considerable difference between the two. 


with whom he can discuss and settle difficult 
points quickly, and usually in person. 

It provides a means of giving the architect, 
engineer or contractor immediate service in 
case of need. Our men have submitted drawings 
within an hour after the request reached 
them, 

It insures, on our part, a clearer understand- 
ing of what is needed than would be possible 
if the details were handled by correspondence 
from the Home Office. 

It gives our detail men a personal contact 
with the builders in their territory, and with 
this contact comes a real enthusiasm to see that 
they are served promptly and well. 

It eliminates a tremendous waste of time and 
a large volume of correspondence, irksome both 
to the customer and to ourselves. 


Manufacture and Distribution 


Orders arrive at our factory—clean— 
the first step in accurate and prompt 
manufacture. 


The most popular types of Fenestra 
are stocked in a score of warehouses 
over the United States, to provide im- 
mediate delivery. The next most 
popular types are kept at Detroit, 
with bars machined and ventilators in 
stock, ready for final assembly and 
shipment. 

In Oakland, California, a branch 
factory is equipped to supply Windo- 
Walls for buyers west of the Rockies, 
thereby saving time and freight 
charges. A similar branch factory is 
located in Toronto to supply Canada. 


Erection 

And finally, our Erection Depart- 
ment—The Fenestra Construction 
Company—with 10 branch offices and 
27 experienced field superintendents, 
insures that our product will be cor- 
rectly installed. These offices assume 
the responsibility as soon as the sash 
leave the factory and carry the job 
through to completion, and final 
approval. 


We believe, therefore, that ‘‘Fenestra’’ has much more to offer the pros- 
pective buyer than merely a carefully made product of national reputation. 
We would like to have you think of Fenestra as a service which includes 
all of the essentials, which together produce a ‘‘satisfactory window 


installation.”’
